5x+65°=180°

5x=180°-65°

=115°

x=115÷5

jose bought 4 comic books and 2 nonfiction books. the 4 comic books cost him 8y dollars.if the cost of one nonfiction book is (3

professor190 [17]

write out the equation:

8y=3+7y (I'm assuming y is the amount of comic books)
8=3+7
8=10

Obviously the equation isn't equal. The nonfiction is greater. By the way, I took out the y because I assumed that y was the amount of books and there was no need to write out 8 times one. On a test, make sure you specify this of the teacher may take off points, if she is using Common Core.

NEED HELP FAST!!!!! The graph below compares plant height to the age of the plant, in weeks. Y=1.3x-0.8 Based on the graph, whic

salantis [7]

Answer:

C) 6 inches

Step-by-step explanation:

Given function:

$Y=1.3x-0.8$

The function compares plant height in inches to the age of plant in weeks.

So, we can say

$Y$ represents height of plant in inches.

$x$ represents age of the plant in weeks.

In order to predict the height of the plant in 5 weeks, we will plugin $x=5$ in the given function and evaluate $Y$

⇒ $Y=1.3(5)-0.8$

⇒ $Y=6.5-0.8$

⇒ $Y=5.7$ inches

Thus the approximate height of plant in 5 weeks would be $\approx 6$ inches

Solve a triangle when A=15° B=113° and b=7?

JulsSmile [24]

Let us draw a triangle ABC with A=15° ,B=113° and b=7.

Please see the attached image.

We know that the sum of interior angles of a triangle is 180 degrees. Thus, we have

$A+B+C=180\\
\\
15+113+C= 180\\
\\
C=62^{\circ}$

Apply Sine rule in the triangle ABC, we get

$\frac{a}{\sin 15}= \frac{7}{\sin 113}\\
\\
a=\frac{7 \sin 15}{\sin 113}\\
\\
a=1.97\\
\\
\text{Again apply sine rule, we get}\\
\\
\frac{c}{\sin 62}= \frac{7}{\sin 113}\\
\\
c=\frac{7 \sin 62}{\sin 113}\\
\\
c=6.71$

Therefore, we have

$a=1.97\\
c=6.71\\
C=62^{\circ}$
