Answer:
Step-by-step explanation:
2a + 4b + 8 + 5
2a + 4b + 13
The two expressions are equivalent because they have the same value regardless of the number of substituted in for y
Answer:
The answer SHOULD be 7/8=224/x;256 pounds.
You may have made a mistake in inputting it here on Brainly. So look for the one that matches that.
Step-by-step explanation:
This is what we know:
Jasper = 224 pounds
Balin = x
Jasper = 7/8 of x
Now we make an equation for that:

To match the selections we will isolate 7/8 on one side of the equation:

Using ratio and proportion we can solve for what x is. Multiply 224 by 8 and divide it by 7. Or you can do it this way too:




So x = 256 pounds
