In a triangle the midline joining the midpoints of two sides is parallel to the third side and half as long ⇒

2(3x + 2) = 2x + 20
6x + 4 = 2x + 20
6x - 2x = 20 - 4
4x = 16
x = 16/4
x = 4

midsegment = 3x + 2 = 3*4 + 2 = 12 + 2 = 14

a pineapple is 7 times as heavy as an orange. the pineapple also weight 870 grams more than orange what is the total weight in g

Alex Ar [27]

An orange ... o grams = ?
a pineapple ... p = 7 * o
p = 870 grams + o

If you would like to know what is the total weight in grams for the pineapple and orange, you can calculate this using the following steps:

7 * o = 870 + o
7 * o - o = 870
6 * o = 870 /6
o = 870 / 6
o = 145 grams

p = 7 * o = 7 * 145 grams = 1015 grams

Result: A pineapple weights 1015 grams and an orange 145 grams.

Change this radical to an algebraic expression with fractional exponents. √y^2 The exponent on y is:

Wewaii [24]

The power rule (or law of indices) related to root is given
$x^{ \frac{1}{2} }= \sqrt[2]{x}$

We have $\sqrt{ y^{2} }$
Rewrite according to the rule we have $y^{ \frac{2}{2} } = y^{1}$

The exponent on y is '1'

Look at the information below. The sum of the measures of angle M and angle R is 90°. © The measure of angle M is (5x + 10). The

kupik [55]

Answer:

Solution given;

<M=5x+10

<R=55

<M+<R=90°

5x+10+55=90°[is a required equation]

now solving it

5x=90-65

5x=25

x=25/5

x=5is your answer.
