Natalija [7]2 years ago
8 0

\text{The two angles are supplementary, so their measures add up to 180 degrees.}

~~~~~~15x+105 = 180\\\\\implies 15x = 180 -105\\\\\implies 15x = 75\\\\\implies x =\dfrac{75}{15}\\\\\implies x = 5

Lincoln middle school plans to collect more than 2,000 cans of food in a food drive. So far, 668 cans have been collected. WRITE
AURORKA [14]
Let x be the unknown number.

7x + 668 < 2000     => 7x plus 668 is less than 2000

where:
7x => x represents the number of cans to be collected in 7 days
668 is the number of cans already collected.
2000 is the target number of cans.

7x  +  668    <    2000
 <u>       - 668           -668</u>
7x                <   1332
<u>÷7                        ÷7</u>
x                  <    190.30
or
x < 190

To check:

7x + 668 < 2000
7(190) + 668 < 2000
1330 + 668 < 2000
1998 < 2000

Delicious77 [7]

Answer:

20 %

Step-by-step explanation:

% Increase = Increase/Original value × 100 %

Data:

 Original = $25

This year = $30

Calculations:

   Increase =  This year - original

                  =         30       -      25

                  =                   $5

% Increase = 5/25 × 100 %

                  = 20 %

The percent increase of the price of the necklace was 20 %.

What is the vaule of y
devlian [24]
Y is equal to 54. (B)

A triangle has a total degree of 180. Given that two of the angles are the same and the last angle is 72 degrees, you can subtract 72 from 180 to get 108. From there, You can divide 108 by 2 (because there are two equal parts) to get 54.
