$25 times 45 equals $1125. Twice as many students as adults so, 45x2=90 90x$12= $1080 $1125+1080=$2205
Answer: the two numbers are 6 and 10
Step-by-step explanation:
Answer:
In this equation, the value of x is 9.
Step-by-step explanation:
-4(6x + 3) = -12(x + 10)
Distribute -4 to (6x + 3) and distribute -12 to (x + 10).
-24x - 12 = -12x - 120
Add 12x on both sides of the equation.
-12x - 12 = -120
Add 12 on both sides of the equation.
-12x = -108
Divide -12 on both sides of the equation.
x = 9
The value of x in this equation is 9.
Answer:
x= 26.25
Step-by-step explanation:
4 times x(26.25)=105 like the prism on the right.
HG =425 deg.
Answer:
y = 5
Step-by-step explanation:
This is a multi-step equation, so you can solve for the variable 'y' by using a series of steps:
1. Combine like terms:
-4y - 3 = 5 - 3y + 6 -19 or -4y - 3 = -3y - 8
2. Isolate the variable using inverse (opposite operations):
Add 8 to both sides: -4y - 3 + 8 = -3y - 8 + 8 or -4y + 5 = -3y
Add -4y to both sides: -4y + 5 + 4y = -3y + 4y
3. Solve for 'y'
5 = y
