Step-by-step explanation:
i got it right
A + b = 87
a = b - 11
b - 11 + b = 87
2b - 11 = 87
2b = 87 + 11
2b = 98
b = 98/2
b = 49 <===
a = b - 11
a = 49 - 11
a = 38 <===
This one is worded oddly, but I think it's going to be:
(2x)/19
Answer:
Length = 16.3 in and Width = 12.3 in
Step-by-step explanation:
Let's name L the length and W the width of the rectangle. We can then write equations describing the statements given:
"<em>the length of a rectangle is 4 more than the width</em>"
L = W + 4
"<em>the perimeter of the rectangle is 57.2 inches</em>"
2 L + 2 W = 57.2
(where we used the formula for the perimeter of the rectangle equal to twice the rectangle's length plus twice the rectangle's width)
Now we use the first equation to substitute for L in the second one:
2 ( W + 4) + 2 W = 57.2
use distributive property to remove parenthesis
2 W + 8 + 2 W = 57.2
combine like terms
4 W + 8 = 57.2
subtract 8 from both sides
4 W = 57.2 - 8 = 49.2
divide both sides by 4 to isolate W
W = 49.2 / 4 = 12.3 in
Now we use this result in the first equation we wrote, to find L
L = W + 4 = 12.3 + 4 = 16.3 in
Therefore : Length = 16.3 in and Width = 12.3 in
Answer:
Subtract 3 x 3 x from both sides of the inequality. Divide each term by - 2 − 2 and simplify. Tap for more steps... Divide each term in - 2 y < 10 - 3 x − 2 y < 10 − 3 x by - 2 − 2. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign
