Answer:
2x = y
Step-by-step explanation:
x is how many bracelets made and each bracelet takes 2 minutes to make so x times 2 or 2x and y is the total time took so 2x=y
if you could anwser the second question that would be great caus e i only get to do this proble once :) no explanation needed
Angle 1 and 2 are equal because of correspondence angle
so , (78-2x) = (89-3x)
x = 89 - 78
x = 11
hence angle 1 = ( 78 - 2*11) = 56
and angle 2 = ( 89-3*11) = 56
So, both of angle is 56
hope it help and your day will full of happiness
Explain how to solve the equation 21 = m +14. What is the value of m?
Enter your explanation and answer in the space provided.
Answer:
m = 7
Step-by-step explanation:
21 = m + 14
21 - 14 = m
m = 7

Show your step by step process.
Solve the system of linear equations.
Answer:
x=1 and y= 5[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
To solve this, lets take the first equation and find the x value.
Because it is ordered in standard form, we need to convert to slope-intercept form, and isolate the y.
5x+4y=16
-5x -5x
4y=-5x+16
÷4 ÷4 ÷4
y=[tex]\frac{-5}{4}[/tex]+4
or
y=-1[tex]\frac{1}{4}[/tex]+4
or
y= 5[tex]\frac{1}{4}[/tex]
Now that we have the y value, we can use this to find the x value by inserting it into either equation, since they both have y values in them. Going with the first one again, lets try it:
5x+4([tex]\frac{-5}{4}[/tex]+4)=16
5x-5+16=16
5x+11=16
-11 -11
5x=5
÷5 ÷5
x=1 and y= 5[tex]\frac{1}{4}[/tex]
If f(1) = 9 and f(n) = 4f(n − 1) then find the value of f(4).
Answer:
576
Step-by-step explanation:
f(2) = 4f(1) = 4*9 = 36
f(3) = 4f(2) = 4 * 36 = 144
f(3) = 4f(3) = 4 * 144 = 576

2-(3x+5)=5-2x
i have too answers but need the right one lol
Answer:
x = -8
Step-by-step explanation:
2 - (3x + 5) = 5 - 2x
Subtract 2 from each side.
-(3x + 5) = 3 - 2x
Apply the negative sign in front of the parentheses.
-3x - 5 = 3 - 2x
Add 5 to both sides.
-3x = 8 - 2x
Add 2x to both sides.
-x = 8
We can't have a negative x value, so we'll need to multiply each side by -1.
x = -8
Hopefully, this helped and wasn't too confusing!
Answer:
Solution given;
2-(3x+5)=5-2x
2-3x-5=5-2x
-3-5=3x-2x
x=-8 is your answer
2/3x + 1/4 = 46/6x - 1/3
Answer:
x = 1/12
Step-by-step explanation:
2/3x + 1/4 = (8x+3) /12 (create equivalent fractions with a denominator of 12)
23/3x - 1/3 = (23x - 1) /3 *(46/6x = 23/3x)
8x + 3 = 23x - 1
12 3
now cross-multiply:
3(8x + 3) = 12(23x - 1)
24x + 9 = 273x - 12
9 = 252x - 12
21 = 252x
x = 21/252 which reduces to 1/12
Ali has invited 18 adults and 6 children to a cookout.
Mo, Ali’s best friend, suggests that Ali seat an equal number of adults and an equal number of children at each table.

-7m²-10m+17
common factor
Answer:
Greatest common factor of 17
So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!
Step-by-step explanation:
Add and subtract the second term to the expression and factor by grouping.
- (m - 1 )( 7m + 17 )
In a sale all the prices are reduced by 30%. Calculate the sale price of the following items
a bike that cost £250
b. a pair of gloves that cost £3.20
Answer:
A: 26.89
B: 0.96
Step-by-step explanation:
70 percent of 250 is 26.89. 70 percent out of 3.20 is 0.96.
Write an equation in slope intercept form (y=max+b) for the line passing through the points. Show your algebraic solving steps.
(-2, -1) and (2,3)
Find the gradient first
m = (y2-y1)/(x2-x1) = 3-(-1)/2 - (-2) = 4/4 = 1
then find the equation of the... slope ._.
y - y1 = m(x - x1)
y - (-2) = 1(x - 3)
y + 2 = x - 3
y =x -3 - 2
y = x - 5
So the equation is y = x - 5

s y=x+7
y = 6x + 2
Solution:
How do you solve this
Step-by-step explanation:
y=x+7........eqni
y=6x+2.....eqnii
putting the value of x in eqnii
y=6x+2
or, x+7=6x+2
or, 7-2=6x-x
or 5= 5x
hence,x=1
sbstutuung the value of x in eqni,
y= x+7
=1+7
=8
hence the value of y is 8

In a shipment of shirts to a clothing store, 2/5 of the shirts are blue and 3/10 of the shirts are red. If there are 20 shirts in the shipment, how many shirts are either blue or red?
Answer: 14
Step-by-step explanation:
Fraction of blue shirts = 2/5
Fraction of red shirts = 3/10
Number of shirts in the shipment = 20
The number of shirts that are either blue or red will be:
= (2/5 + 3/10) × 20
= (4/10 + 3/10) × 20
= 7/10 × 20
= 14
The number of shirts that are either blue or red is 14

7. What is the slope of the line that passes through the points (14, -18) and (5, -12)?
Answer:
slope =[tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope, or [tex]m[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:
[tex]m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}[/tex]
Thus, the slope is [tex]-\frac{2}{3}[/tex].
Camille's birthday party will cost $32 if she invites 16 guests. How many guests can there be, at most, if Camille can afford to spend a total of $48 on her birthday party? Assume the relationship is directly proportional.
Answer:
I think its gon be 24 guests
Answer:
24 people can be there at most :)
Step-by-step explanation:
$32 divided by 16(guests) is $2
so its $2 per person
so 48$ divided by $2 is 24
So Camille can invite 24 people at the cost of 48$ being her total at most :)
