expand 2x - 5 and x-3
Answer:
2x^2 - 11x + 15
Step-by-step explanation:
Expand 2x - 5 and x - 3 means that the algebraic expressions be multiplied.
(2x - 5)(x - 3)
x(2x - 5) -3(2x - 5)
2x^2 - 5x - 6x +15 = 2x^2 - 11x + 15

w=6
Step-by-step explanation:
w=6
If you double 5 on the bottom to get 10, you will also have to double 3 on the top.
An easy way you could do this is by cross products. 3(10)=5(w). w=6
Answer:
w = 6
Step-by-step explanation:
3/5 = w/10
Cross multiply.
10 × 3 = 5 × w
Multiply.
30 = 5w
Divide 5 on both sides.
30/5 = w
6 = w
Maria, Max, Molly, and Mitch are all picking apples at an orchard. The number of apples Max picks is the number of apples Maria picks squared. Molly picks the number of apples that Max and Maria pick combined. Mitch picks the number of apples Molly picks squared plus the number of apples that Maria picks. If Maria picks 3 apples, then how many apples does Mitch pick
Answer:
147
Step-by-step explanation:
Given: Maria=3
Max=3 squared=9
Molly=Max+Maria=9+3=12
Mitch=Molly squared+Maria=144+3=147
Hope this helps!
Solution:
Since Max picks the number of apples that Maria does but squared, then Max picks 3^2=3 * 3=9 apples. Since Molly picks the number of apples that Maria picks plus the number that Max picks, Molly picks 3+9=12 apples. Finally, Mitch picks the number Molly picks squared plus the number Maria picks, so Mitch picks 12^2+3=12 * 12 +3=144+3=147 apples.

What is an expression equivalent to
8
with a denominator of 11d.
11
Answer: 88/11.
Step-by-step explanation:
We want to find a expression, with a denominator of 11, that is equivalent to 8.
remember that if we have the expression A/B
the numerator is A, and the denominator is B.
Then we have:
A/11 = 8
we need to find the value of A.
To do this, we can multiply by 11 in both sides of the equation:
(A/11)*11 = 8*11
A = 88
Then the expression is:
88/11.

2p+8=20-p what is the value of p??
Answer:
4
Step-by-step explanation:
3p+8=20
3p=12
p=4
Answer:p=4
Step-by-step explanation:
2p+8=-p+20
Step 2: Add p to both sides.
2p+8+p=-p+20+p
3p+8=20
Step 3: Subtract 8 from both sides.
3p+8-8=20-8
3p=12
Step 4: Divide both sides by 3.
3p/3=12/3
p=4
\The sphere's radius is half the radius of the hemisphere. How does the volume of this hemisphere compare with the volume of the sphere?
Answer:
4 : 1 or 4 times
Step-by-step explanation:
V of sphere is
V = 4/3 π r³
then we can compare both of them dirextly
Vs : Vhs
4/3 π r³ : ½ (4/3 π (2r)³)
4/3 π r³ : ½ * 4/3 π 8r³
1 : ½ * 8
1 : 4
Vhs : Vs = 4 : 1
so the volume of hemisphere is 4 times bigger than the sphere.
Answer:
It is greater than the volume of the sphere.

3. Nancy and Harry are sliding a stone statue and moving it to a new location in their garden. Nancy is pushing the statue with a force of 120N at a 60° angle to the horizontal and Harry is pulling the statue with a force of 180N at a 40° angle with the horizontal. What is the magnitude of the horizontal force exerted on the statue?
Answer:
197,8879 N.
Step-by-step explanation:
The magnitude of the horizontal force exerted on the statue can be calculated using trigonometric functions.
The question given says that Nancy is pushing the statue with a force of 120 N at a 60° angle to the horizontal and Harry is pulling the statue with a force of 180 N at a 40° angle with the horizontal.
With that information can be calculated the horizontal force exerted on the statue by Nancy, the horizontal force exerted on the statue by Harry and, adding that results, the total horizontal magnitude can be calculated.
The cosine function can be used to calculate the horizontal component of the forces exerted by Nancy and Harry, to determine the horizontal component of the force exerted on the statue.
F= (120 N cos 60°) + (180 N x cos 40°)
F= 197,8879 N

Answer:
Circumference of a circle is 2πr
where r is the radius
radius = diameter/2
diameter = 4.6km
radius = 4.6/2 = 2.3km
Circumference = 2 × π × 2.3

solve for q 5q + 2p + 4 = 3q – 8
Answer:
q = -6 - p
Step-by-step explanation:
By collecting the like terms , we have:
5q - 3q = - 8 - 4 - 2p
2q = -12 - 2p
divide each term by 2 , we have
q = -6 - p
Answer:
q=-6-pSolution,
[tex]5q + 2p + 4 = 3q - 8 \\ or \: 5q - 3q = - 8 - 4 - 2p\\ or \: 2q = - 12 - 2p \\ or \: q = \frac{ - 12 - 2p}{2} \\ q = - 6 - p[/tex]

Can someone help me with the below question???
Answer:
so 2a+3b=±13
Step-by-step explanation:
4a²+9b²=97
ab=6
2a+3b=?
by using formula
(a+b)²=a²+b²+2ab
(2a+3b)²=(2a)²+(3b)²+2(2a)(3b)
(2a+3b)²=4a²+9b²+12ab
putting values
(2a+3b)²=97+12(6)
(2a+3b)²=97+72
(2a+3b)²=169
taking square root on both sides
√(2a+3b)²=√169
2a+3b=±13
i hope it will help you
Answer:
2a+3b = 13
Step-by-step explanation:
Using this formula
[tex](x+y)^2 = x^2+y^2+2xy[/tex]
Where,
x = 2a and y = 3b
Putting in the above formula
=> [tex](2a+3b)^2=4a^2+9b^2+12ab[/tex]
Putting 4a²+9b² = 97 and ab = 6
=> (2a+3b)² = 97+12(6)
=> (2a+3b)² = 97+72
=> (2a+3b)² = 169
Taking sqrt on both sides
=> 2a+3b = 13
Athena is going to draw one marble from a paper sack. Inside the sack, there are 6 blue marbles, 6 black marbles, 3 green marbles, and 2 purple marble. What is the complement to the probability that she will draw a purple marble? A 16/17 B 15/17 C 13/17 D 2/7
Answer:
D. 2/17
Step-by-step explanation:
Add all of the marbles: 6 blue marbles + 6 black marbles + 3 green marbles + 2 purple marbles = 17 marbles altogether.
Since there are 2 purple marbles out of 17 marbles in the paper sack, the complement to the probability that she will draw a purple marble is 2/17.

Erin has x working toys and y broken toys. Bert plays with Ernie's toys and breaks 1/3 of the working toys. Ernie then throws aways 1/4 of all of the broken toys. In terms of x and y, how many toys did Ernie throw away,
Answer:
y/4 + x/12
Step-by-step explanation:
The number of working toys = x
The number of broken toys = y
Bert breaks 1/3 of the working toys, that is:
1/3 * x = x/3
The number of broken toys is now:
y + x/3
Ernie then throws away 1/4 of the broken toys. In terms of x and y, the number of broken toys that Ernie threw away is:
1/4 *(y + x/3)
= y/4 + x/12
The perimeter of a rectangle is 86cm. Its shortest side has a length of 16cm. State the length of the longest side.
Answer: length = 27 cm
Step-by-step explanation:
Perimeter = 2(l + w)
86 = 2(l + 16)
86 = 2l + 32
86 - 32 = 2l
l = 54/2 = 27 cm.

Which point is located at (4, –2)? On a coordinate plane, point A is 2 units to the left and 4 units up. Point B is 4 units to the right and 2 units down. Point C is 4 units to the left and 2 units up. Point D is 2 units to the right and 4 units down. A B C D
Answer:
Point B is 4 units to the right and 2 units down
Step-by-step explanation:
Since our x is positive, we are going to the right of the x-axis (where positive values lay).
Since our y is negative, we are going down in the y-axis (where negative values lay).
Answer: point B matches (4,-2)
Step-by-step explanation:
Within parentheses, the first number is the x-coordinate. Positive numbers are given without the +sign and they go to the Right. Negative -numbers go to the left.
The second number is the y-coordinate. Positive numbers go up, -numbers that are negative go down.
In this example it will be 4 Right and 2 Down.
What is the solution to this equation?

O A. x= 10
O B. x= 4
O c. x = 12
O D. x= 6
Answer:
B.
Step-by-step explanation:
The quickest and fastest way to do this is to guess and check. Simply plug in the given values one by one into a calc and you should see that x = 4 works.
Answer:
x=4
Step-by-step explanation:
7x-2(x - 10) = 40
Distribute
7x -2x +20 = 40
Combine like terms
5x +20 =40
Subtract 20
5x +20 -20 = 40-20
5x= 20
Divide by 5
5x/5 = 20/5
x =4
Which graph shows a dilation?
The graph that shows a dilation among the given graphs is; Graph 1.
Dilation in graphs simply means each side is multiplied by the samescale factor. What this means is that the ratio of each dilated side to their
respective old sides before dilation must be the same scale factor.
First Graph; We can see it is a rectangle and the pre-dilated image has
2 units along the y - axis and 4 units across the x-axis. After dilation, it now
has 4 units along the y - axis and 8 units across the x-axis. This means the
scale factor in both axis are; 4/2 = 2 and 8/4 = 2. They are both the same
scale factors and as such this graph shows a dilation.
For the second, third and fourth graphs, the scale factors after dilation
are not equal for both axis and as such they do not represent dilation.
