What’s are the answers for both?

Mathematics
1 answer:
nevsk [136]3 years ago

Answer:

<h2>d = 8</h2><h2>g = 2</h2>

Step-by-step explanation:

8d + 4 = 5d + 28

Group like terms

That's

8d - 5d = 28 - 4

3d = 24

Divide both sides by 3

d = 8

\frac{7(7g + 8)}{4}  = 38.5

Cross multiply

we have

7(7g + 8) = 38.5(4)

49g + 56 = 154

49g = 154 - 56

49g = 98

Divide both sides by 49

g = 2

Hope this helps you

Simple interest formula:

i = Prt

where
i = interest earned
P = principal amount invested
r = interest rate
t = time

In this problem, we are looking for i.
P = $10,000
r = 3.5% = 0.035
t = 7 years

i = Prt

i = $10,000 * 0.035 * 7 = $2,450

The amount of interest earned in the 7 years is $2,450.
The interest is added to the principal amount that was invested, so after 7 years, David has $10,000 + $2,450 = $12,450

Perpendicular lines aretwo distinct coplaner lines that intersect to form what type of angle?
Tcecarenko [31]
If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. If two sides of two adjacent angles are perpendicular, then the angles are complementary.

If there is a line and a point not on the line, then there is exactly one line through the point perpendicular to the given line.

Apply the distributive property to factor out the greatest common factor.<br> 90+27=?
Lady bird [3.3K]

Answer:

<h2>9 × (10 + 3)</h2>

Step-by-step explanation:

The distributive property:

<em>a × (b + c) = a × b + a × c</em>

90 = 9 × 10

27 = 9 × 3

90 + 27 = 9 × 10 + 9 × 3 = 9 × (10 + 3)
