please solve this for me

Let's solve your system by substitution.

y=2x+1;y=4x−1

Step: Solve y=2x+1for y:

y=2x+1

Step: Substitute2x+1foryiny=4x−1:

y=4x−1

2x+1=4x−1

2x+1+−4x=4x−1+−4x(Add -4x to both sides)

−2x+1=−1

−2x+1+−1=−1+−1(Add -1 to both sides)

−2x=−2

−2x

−2

=

−2

−2

(Divide both sides by -2)

x=1

Step: Substitute1forxiny=2x+1:

y=2x+1

y=(2)(1)+1

y=3(Simplify both sides of the equation)

Answer:

x=1 and y=3

Answer:

Step-by-step explanation:

Given function is,

y = x + 4.5

To complete the input-output table given in the picture we will substitute the values of x in the function rule,

For x = 1,

y = 1 + 4.5

y = 5.5

For x = 3

y = 3 + 4.5

y = 7.5

Therefore, complete table will be,

x         0          1          2         3        

y        4.5       5.5      6.5      7.5

Answer:

x=216

n=18

m=5

x=-11

Step-by-step explanation:

12= x/18

Can also be written as 12=x÷18. Multiply each side by 18 to isolate x and to find the value of x.

This will cause the equation to look like 12×18=x÷18×18. This will eliminate 18 from the right side of the equation and for 12×18 to equal 216. After simplifying it will equal:

x=216

3=n/6

Can also be written as 3=n÷6. Multiply each side by 6 to isolate n in order to find the value of n.

This will cause the equation to look like 3×6=n÷6×6. After simplifying the equation by causing the 6 on the right side of the equation to cancel out and multipyling 3 and 6 together, it will equal:

n=18

-10=m+(-15)

Add 15 to each side of the equation to find the value of m.

This will cause the equation to look like -10+15=m+(-15)+15. This will cause the 15s on the right side of the equation to cancel out and for the left side of the equation to equal 5. After doing this, the equation will equal:

5=m

-7+x=-18

Add 7 to each side of the equation to isolate x in order to find the value of x.

This will cause the equation to look like -7+7+x=-18+7. This will cancel out the 7s on the left side of the equal and the right side of the equation will equal -11. After using these steps to simplify, the equation will equal:

x=-11

Answer:

T-shirt : £11

Hat : £7

Step-by-step explanation:

Think of T-shirts as T

and Hats as H

5t + h = 62

2t + h = 29  

we then subtract them both to cancel out h

3t = (62-29) = 33

now we divide 33 by 3  to find one t

33/3 = 11

so one t shirt is £11.00

now we substitute it back into the equation

2t ( 2x11 ) = 22

22 +h = 29

29 - 22 = 7

Answer:

Step-by-step explanation:

Carry out indicated operations to see if they are equal

2(6-3x)+x=2(3x)+x+12

2(6)+2(-3x)+x=6x+x+12

12-6x+x=6x+x+12 combine like terms on both sides

12-5x=12+7x (we can see here they are unequal but we can continue) subtract 12 from both sides

-5x=7x divide both sides by x

-5=7

7 is not equal to -5 so the original expressions aren’t equivalent.

Answer:

800

Step-by-step explanation:

100x216=27

21600 divided by 27=800

The total budget for this student film was 800$.

A percent is a quantity or ratio that, in mathematics, represents a portion of one hundred. A dimensionless relationship between two numbers can be represented in a variety of ways, such as through ratios, fractions, and decimals. The symbol "%" is frequently written after the number to indicate percentages. Additionally, you can indicate them by adding "percent" or "pct" after the number.

Given, A bunch of buddies was producing a school movie. Their whole budget was spent on props and equipment. Equipment cost $216, while props accounted for 73% of the whole budget. Hence,

Percent of their budget they spent on equipment = 100 - 73 = 27

Also given the money spent on budget = 216

Thus, 27 % of the total budget = 216

1 % of the total budget = 8

Total budget = 8 *100

Therefore, This student movie had an 800-dollar budget in total.
