Answer:
x = -19; y = 25/3
Step-by-step explanation:
Step 1: solve the equation with only one variable
Isolate the variable (x)
x + 10 = -9
x = -9 - 10
x = -19
Step 2: input new information into the other equation
If x = -19, then:
2(-19) - 6y = 12
Isolate the variable (y)
-38 - 6y = 12
-6y = 12 + 38
-6y = 50
y = 50 ÷ 6
y = 50/6
Simplify
y = 25/3
The new triangle is gonna be bigger. But how big? Let’s look at A.
A= 2,8
Look at A’, it’s 6,24. See a pattern??
Multiply 2,8 by 3. It’s triple the amount, therefore the scale factor is 3.
To double check, multiply by 3 to B and C and see what you get.
Answer:
4 scoops
Step-by-step explanation:
The recipe calls for 6 scoops
He is making 2/3 of the recipe
Multiply these together
2/3 * 6 =
2/3 *6/1 =
4 scoops
3miles/ 28 minutes times 42 minutes is equal to 4.5 miles.
Therefore, Eric run 4.5 miles in 42 minutes.
Hopefully this helps!
