How to get the base of a parallelogram that has a area of 26 1/2 and a height of 6 5/8?
ioda
The area of all paralellograms can be found by
area=base times height

so
area=26 and 1/2
height=6 and 5/8
convert to improper fractions for ease of use
26 and 1/2=52/2+1/2=53/2
6 and 5/8=48/8+5/8=53/8
so

area=height times base
53/2=53/8 times base
multiply both sides b 8/53 so that we clar the fraction (53/8 times 8/53=424/424=1)
(53 times 8)/(53 times 2)=1base
8/2=1base
4=base

answer is base=4 units

Which step shows the result of applying the subtraction property of equality?<br> (12x+8)+4-3
Nadya [2.5K]

Answer:

Value of expression = -3 / 4

Step-by-step explanation:

Given:

(12x + 8) + 4 = 3

Find:

Value of expression

Computation:

Given expression

(12x + 8) + 4 = 3

Step 1: Use Distributive property

12x + 8 + 4 = 3.

Step 2: By adding like terms.

12x + 12 = 3

Step 3: Transfer

12x = 3 - 12

Step 4: Subtract

12x = -9

Step 4: Divide both sides by 12

12x / 12 = -9 / 12

x = -3 / 4

Value of expression = -3 / 4
