Answer:

a = -8

Step-by-step explanation: Subtract 100 on both sides to isolate the variable. From there you will have 11a = -88. If you divide on both sides to cancel them out you will get you answer for the variable -8.

nadya68 [22]

Answer:

y = 4x +1

Step-by-step explanation:

6x + 1 = y + 2x

First you need to solve for y, so then you need to

1. Combine like terms

So since there isn't anything to combine we can more on.

2. Make Y by itself

You need to subtract the 2x from both side to get the answer

Tell whether each pair of angle measurements are complementary, supplementary or neither.  36°,24°  18°,72°  96°,84°
Serggg [28]

Given:

The pairs of angles are:

36°,24°

18°,72°

96°,84°

To find:

Whether each pair of angle measurements are complementary, supplementary or neither.

Solution:

Two angles are complementary if there sum is 90 degrees.

Two angles are supplementary if there sum is 180 degrees.

For 36° and 24°,

36^\circ+24^\circ =60^\circ

So, this pair is neither complementary not supplementary.

For 18° and 72°,

18^\circ+72^\circ =90^\circ

So, this pair is complementary.

For 96° and 84°,

96^\circ+84^\circ =180^\circ

So, this pair is supplementary.

If S is the midpoint of RT , RS=8x+11 and ST =14x-1 find x
garri49 [273]

Answer:

From the given, we establish this relationship:

RS + ST = RT

RS = ST since S is the midpoint of RT

Thus, let's use RS = ST to find x,

By substituting the given expressions:

RS = ST

8x + 11 = 14x - 1

12 = 6x

x = 12/6

thus,

x = 2
