Answer:

The answer is 63 to 90.

Other ways to show this are: 63:90 or 63/90

Explanation:

The first number would be the amount of boys there (we already know how many there are). The second number would be the total amount of students. To know the total number of students, We would have to add the number of boys and girls (63 + 27) to get the sum of 90.

Now, since we know the total amount of students, we know that the answer is 63 to 90.

Eddie's Evergreens sells Christmas trees and wreaths. Trees cost 3 dollars more than 4 times the price of each wreath. It costs

kari74 [83]

Answer:

$W = 16$

$T = 67$

Step-by-step explanation:

Represent trees with T and wreaths with W

Given

$T = 3 + 4 * W$

$2 * W + T = 99$

Solving (a): Cost of W

Substitute 3 + 4 * W for T in the second equation

$2*W + 3 + 4 * W = 99$

$2W + 3 + 4 W = 99$

Collect Like Terms

$2W + 4 W = 99 - 3$

$6W = 96$

Divide through by 6

$W =\frac{96}{6}$

$W = 16$

Hence, each wreath costs $16

Solving (b): Cost of T

$T = 3 + 4 * W$

Substitute 16 for W

$T = 3 + 4 * 16$

$T = 3 + 64$

$T = 67$

Hence, each tree costs $67

A)12/35 B)37/35 C)12/37 D)35/12 Please help

Licemer1 [7]

It's 12/35 because tangent is opposite over adjacent, so 12 is opposite of angle M and 35 is adjacent of angle M

If you want to remember cosine, sine, and tangent just remember
