Answer:

Step-by-step explanation:

Simplifying

d + -5 = 7

Reorder the terms:

-5 + d = 7

Solving

-5 + d = 7

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '5' to each side of the equation.

-5 + 5 + d = 7 + 5

Combine like terms: -5 + 5 = 0

0 + d = 7 + 5

d = 7 + 5

Combine like terms: 7 + 5 = 12

d = 12

Simplifying

d = 12

What 75% of two hundred

Ghella [55]

To find 75% of 200, we can multiply two fractions.

75/100 * 200/1

Now, just multiply the numerators and the denominators separately.

75 * 200 = 15000

100 * 1 = 100

Now, divide.

15000/100 = 150

If EH = 76, calculate DI.

Montano1993 [528]

Answer:

DI = 38

Step-by-step explanation:

Δ EHC and Δ DIC are similar and ratios of corresponding sides are equal, that is

$\frac{DI}{EH}$ = $\frac{DC}{EC}$ , substitute values

$\frac{DI}{76}$ = $\frac{1}{2}$ ( cross- multiply )

2DI = 76 ( divide both sides by 2 )

DI = 38
