<em>Answer:</em>

<em>In my opinion the answer is </em><em><u>y = 6</u></em>

<em>Step-by-step explanation:</em>

<em>We have two unknowns from the equation therefore, two equations are needed. These equations are: </em>

<em> </em>

<em>3x + y = 9  </em>

<em>y = –4x +10  </em>

<em> </em>

<em>To solve for y, we first substitute the second equation to the first one. </em>

<em>3x + –4x +10= 9  </em>

<em>x = 1 </em>

<em> </em>

<em>We substitute the value of x to either of the equations and solve for y. </em>

<em> </em>

<em>y = –4(1) +10  </em>

<em>y = 6</em>

Answer:

y=6

Step-by-step explanation:

3x + y = 9

y = -4x + 10

Substitute the value of y in the first equation:

3x + (-4x + 10) = 9

Apply the subtraction property of equality:

-x + 10 = 9

-x=-1

x=1

Substitute 1 for x in the given y equation

y = -4x + 10

y = -4(1)+ 10

y=6

A rectangular picture frame has perimeter of 58 inches. The height of the frame is 18 inches. What is the width of the frame?
Stells [14]

Answer:

11 inches

Step-by-step explanation:

A rectangle's perimeter can be found using:

p=2l+2w

We know that the perimeter, p, is 58, and the length/height is 18. Therefore, we can substitute those values in

58=2(18)+2w

Multiply 2 and 18

58=36+2w

Since we want to find the width, we need to get w by itself. First, subtract 26 from both sides

58-36=36-36+2w

22=2w

Since w is being multiplied by 2, divide both sides by 2. This will cancel out the 2, and leave w by itself.

22/2=2w/2

11=w

So, the width is 11 inches

The Westside Bakery uses 310 pounds of flour to make 1,000 loaves of bread. Each loaf
DanielleElmas [232]

Answer:

310 / 1000 = 0.31 pounds

Step-by-step explanation:

When dividing by a number that is 1 less 0 than how many digits the number has, we can move the decimal point the number of times zero is repeated at the end of the number.

1000 has 3 zeroes, so we move the decimal point 3 moves to the left.

So, we do this:

After 0 moves: 310

After 1 move: 31.0

After 2 moves: 3.10

After 3 moves = 0.310

0.310 is the same as 0.31

Therefore, 0.31 pounds of flour are in each loaf.
