7-x=15

7-(-8)=15

what we have to do in order to solve this is change the 2 subtraction signs into a addition sign because a negative plus a negative makes a positive.

Actually, its the other way around, its not 7-x=15 but
$x - 7 = 15 \\ x = 15 + 7 \\ x = 22$

A variety pack of chocolates contains chocolate candies with different fillings. one eighth of the candy has coconut filling, 5/

tino4ka555 [31]

<u>Answer</u> : the number of candies having chocolate cream filling $=26$

Percent of candy has peanut butter filling = 31.25%

Fraction of candy is orange or chocolate cream = $\frac{9}{16}$

<u>Explanation:</u>

Part of candy has coconut filling = $\frac{1}{8}$

Part of candy has peanut butter filling = $\frac{5}{16}$

Part of candy has orange cream filling = $\frac{5}{32}$

Remaining will be chocolate cream filling

= $1-\frac{1}{8}-\frac{5}{16}-\frac{5}{32}\\=1-\frac{4+10+5}{32}\\=1-\frac{19}{32}\\=\frac{32-19}{32}\\=\frac{13}{32}$

Now, we have number of candies with coconut filling =8

so, $\frac{1}{8}\times x=8$ , where x is the total number of candies ,

x = 8×8=64

So, the number of candies having chocolate cream filling=

$\frac{13}{32}\times 64\\=26$

Percent of candy has peanut butter filling = $\frac{5}{16}\times 100\\=\frac{125}{4}$

∴Percent of candy has peanut butter filling = 31.25%

Fraction of candy is orange or chocolate cream

$=\frac{5}{32}+\frac{13}{32}\\=\frac{18}{32}\\=\frac{9}{16}$

∴Fraction of candy is orange or chocolate cream = $\frac{9}{16}$

- Mr. Sanders wants to display his American flag in a triangular case as shown below. 18.5 in What is the area of the triangular

Dmitriy789 [7]

Answer:

The area of the triangular case = 61.2 square inches

Step-by-step explanation:

P.S - The exact question is -

Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.

To find - What is the area of the triangular case ?

Proof -

Given that,

Base of triangle = $14\frac{2}{5}in$

Height of triangle = 8.5 in

We know that,

Area of triangle = $\frac{1}{2}*Base*Height$

= $\frac{1}{2}*8.5*14\frac{2}{5}$

= $\frac{1}{2}*8.5*14.4$

= $\frac{1}{2}*122.4$

= 61.2

∴ we get

The area of the triangular case = 61.2 square inches
