5x−6=3x+10 PLSPLS HELP
Answers
Answer:
x = 8
Step-by-step explanation:
Let's solve your equation step-by-step.
5x−6=3x+10
Step 1: Subtract 3x from both sides.
5x−6−3x=3x+10−3x
2x−6=10
Step 2: Add 6 to both sides.
2x−6+6=10+6
2x=16
Step 3: Divide both sides by 2.
2x /2 = 16/ 2
x=8
Answer:
So x=8 is the answer.
Step-by-step explanation:
5x-6=3x+10
Adding 6 on both sides to find out the value of x
5x-6+6=3x+10+6
5x=3x+16
Subtracting 3x on both sides to find out the value of x
5x-3x=3x-3x+16
2x=16
Dividing 2on both sides
2x/2=16/2
x=8

Daisy walked two-fifths of a mile in one-fifth of an hour. Walking at the same pace, how far will Daisy walk in 1 hour?
Answers
Answer:
2 miles
Step-by-step explanation:
2/5 mile = 1/5 hour
x mile(s) = 1 hour
Cross multiplying.
x · 1/5 = 2/5 · 1
x/5 = 2/5
Multiplying both sides by 5.
x = 10/5
x = 2
Daisy will walk 2 miles in 1 hour.
Answer:
[tex]\Huge \boxed{\mathrm{2 \ miles}}[/tex]
Step-by-step explanation:
2/5 mile = 1/5 hour

The function h is defined as h (x) = 5x² – 3.
Find h(x+1).
Answers
Answer:
h(x + 1) = 5x² + 10x + 2
Step-by-step explanation:
Step 1: Write out function
h(x) = 5x² - 3
Step 2: Plug in x + 1 for x
h(x + 1) = 5(x + 1)² - 3
Step 3: Expand
h(x + 1) = 5(x² + 2x + 1) - 3
Step 4: Distribute
h(x + 1) = 5x² + 10x + 5 - 3
Step 5: Combine like terms
h(x + 1) = 5x² + 10x + 2

Mathematically,
Phrase 1 can be represented as follows;

If f is a differentiable function such that f′(x)≥6, find the largest value of ???? so that f(4)≥???? whenever f(2)=10. (Use decimal notation. Give your answer as exact number.)
Answers
Answer:
12
Step-by-step explanation:
If the slope of the function were exactly 6 on the interval between 2 and 4, then the increase on that interval from f(2) = 10 would be (4-2)·6 = 12. Since the slope is at least 6, the increase is at least 12, so ???? = 10+12 = 22.

The slope of the line is -2.5.
Step-by-step explanation:
The formula to compute the slope of a straight line is:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The graph shows the gift card balance after buying 2 and 5 cups of medium coffee.
The two points provided are:
A = (1, 17.50)
B = (5, 7.50)
Compute the slope of the line as follows:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]=\frac{7.50-17.50}{5-1}\\\\=\frac{-10}{4}\\\\=-2.5[/tex]

find the length of the hypotenuse !!
Answers
Answer:
17
Step-by-step explanation:
To find the hypotenuse, you would use the Pythagorean theorem.
[tex]A^{2} +B^{2} =C^{2}[/tex]
We can plug 8 and 15 into A and B\
[tex]8^{2} +15^{2} =C^{2}[/tex]
We can simplify this to
64+225=[tex]C^{2}[/tex]
289 = [tex]C^{2}[/tex]
To get C by itself not squared, we can do the square root of both sides.
[tex]\sqrt{289} =\sqrt{C^{2} }[/tex]
If we simplify, we get
17 = C or C = 17
Therefore the length of the hypotenuse is 17.

5! The office needs cabinets. The price for the first type of cabinet is $10, it
needs 6 ft2 of floor space, and it has a storage volume of 8 ft. The price
for the second type of cabinet is $20, it needs 8 ft? of floor space, and it
has a storage volume of 12 ft. The company wants to spend no more
than $140 and the office can hold up to 72 ft2 of cabinets. How can the
storage volume be maximized?
Answers
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of 6 ft² to be purchased and y represent the number of 8ft² cabinet to e purchased.
x > 0 and y > 0
6 ft² cabinet cost $10 and 8 ft² cabinet cost $20, only $140 is available to spend, therefore the cost equation is:
10 x + 20 y ≤ 140
Also the office can hold only 72 ft², the space equation is:
6x + 8y ≤ 72
The volume equation is:
V = 8x + 12y
From the graph attached, we have to find the point with maximum volume by testing the point (12, 0), (0,7) , (8,3)
For (12, 0): V = 8(12) + 12(0) = 96 ft³
For (0, 7): V = 8(0) + 12(7) = 84 ft³
For (8, 3): V = 8(8) + 12(3) = 100 ft³
The (8,3) point has the maximum volume. That is 8 6 ft² cabinet and 3 8ft² cabinet

Geometry and Trigonometry
Answers
Answer:
a. 227 cm
b. 495 cm
Step-by-step explanation:
a. Radius of arc = sin(½θ) = 2.10/r
θ = (360-225)/2 = 67.5
Radius of arc = sin(67.5) = 2.10/r
r = 2.10/sin(67.5) = 2.273 m = 227 cm (nearest cm)
b. Length of arc = θ/360*2πr
Take π as 3.14
r = 210 cm
θ = 360 - 225 = 135°
Length of arc = [tex] \frac{135}{360}*2*3.14*210 = 495 cm [/tex] (to nearest cm)
Male children. While it is often assumed that the probabilities of having a boy or a girl are the same, the actual probability of having a boy is slightly higher at 0.51. Suppose a couple plans to have 3 kids. A) Use the binomial model to calculate the probability that two of them will be boys. B) Write out all possible orderings of 3 children, 2 of whom are boys. Use these scenarios to calculate the same probability from part (a) but using the addition rule for disjoint outcomes. Confirm that your answers from parts (a) and (b) match. C) If we wanted to calculate the probability that a couple who plans to have 8 kids will have 3 boys, briefly describe why the approach from part (b) would be more tedious than the approach from part (a). 1) (32)0.512 ∗ 0.49 = 0.3822) BBG,BGB,GBB,GGB,GBG,BGG,GGG,BBBP(2boy) = BBG + GBB + BGBBBG + BGB + GBB + GGB + GBG + BGG + GGG + BBB = 3/8 = 0.375So since boy and girl has slight different probablity, two answer will be different but they are close3) Because using approach, you will have to list all 56 combinations
Answers
Answer:
Step-by-step explanation:
Since the actual probability of having a boy child is 0.51, the probability of having a girl child will be (1 - 0.51) = 0.49
A couple plans to have 3 kids; 2 of whom are boys
(A) Using the binomial model, the probability that 2 of the 3 children will be boys is (2/3) × 0.51 = 0.34
(B) The possible orderings of the 3 children are given below:
B1 B2 G / B1 G B2
B2 B1 G / B2 G B1
G B1 B2 / G B2 B1
Where B1 is one male child and B2 is the other male child
(C) If we wanted to calculate the probability that a couple who plans to have 8 kids will have 3 boys, briefly describe why the approach from part (b) would be more tedious than the approach from part (a)
If the probability of 2/3 is 0.34 then the probability of 3/8 will be 0.1912 when you cross multiply

Solve the inequality for x. –2x + 3 < –13
Answers
Answer:
x > 8
Step-by-step explanation:
When you divide or multiply both sides of an inequality by a negative number, the equality is switched.
-2x + 3 < -13
(-2x + 3) - 3 < -13 - 3
-2x < -16
-2x/-2 < -16/-2
x > 8
Answer:
x > 8
Step-by-step explanation:
In order to solve the inequality for x, we must get x by itself on one side of the equation.
-2x + 3 < -13
3 is being added to -2x. The inverse of addition is subtraction. Subtract 3 from both sides of the equation.
-2x + (3-3) < (-13-3)
-2x < -13 -3
-2x < -16
x is being multiplied by -2. The inverse of multiplication is division. Divide both sides of the equation by -2.
-2x/-2 < -16/-2
When dividing or multiplying by a negative number, remember to flip the inequality sign.
-2x/-2 > -16/-2
x > -16/-2
x > 8
The solution to the inequality is x>8
