The given equation is confusing since it written straight
without any symbols or parenthesis. I can write the equation in two forms:
(1 / 4) d + 7 --->
1
and
(1 / 4 d) + 7 --->
2
For equation 1, the variable d is first multiplied by 1 /
4 before adding up with the number 7. So in this case, the correct phrase would
be something like:
“The sum of one fourth a number and seven”
For equation 2, this is more complicated since the
variable is on the denominator side. The number 1 is divided by the product of
4 and variable d then summed up with the number 7. The correct phrase for this
one would be something like:
“The sum of the quotient of one over four times a number
and seven”
Select which equation is the correct one.
Answer: 5/7 squared
Step-by-step explanation:
To change 7/5 to 1, multiply by 5/7.
To change (7/5)^2 to 1, multiply by (5/7)^2.
Answer:
23
Step-by-step explanation:
area of a trapezoid = 1/2 × (a + b) × h
so, we have
96 = 1/2 × ((4x - 1) + (x + 3)) × 6 = (5x + 2) × 3
32 = 5x + 2
30 = 5x
x = 6
a = 4x - 1 = 4×6 - 1 = 24 - 1 = 23
