Each pair of boots costs $150.
Each pair of boots costs $150.
Two pairs of jeans and three shirts cost the same as one pair of boots.
Two pairs of jeans and three shirts cost the same as one pair of boots.
two pairs of jeans for $25 and three shirts for $15
two pairs of jeans for $25 and three shirts for $15
two pairs of jeans for $25 each and three shirts for $15 each
two pairs of jeans for $25 each and three shirts for $15 each
Using substitution, which number from the set {15, 25, 35, 55} makes the equation y+15=40 true?
To find the value of y that makes the equation y + 15 = 40 true, we can subtract 15 from both sides of the equation:
y + 15 - 15 = 40 - 15
This simplifies to:
y = 25
So the number that makes the equation true is 25.
Using substitution, which number from the set {6, 13, 18, 26} makes the equation 2x+5=31 true?(1 point)
To find the value of x that makes the equation 2x + 5 = 31 true, we can subtract 5 from both sides of the equation:
2x + 5 - 5 = 31 - 5
This simplifies to:
2x = 26
Now, we can divide both sides of the equation by 2 to solve for x:
2x/2 = 26/2
This simplifies to:
x = 13
So the number that makes the equation true is 13.
