Mathematics
1 answer:
anygoal [31]3 years ago
6 0

Answer:

Step-by-step explanation:

Use the fact that C + 118 = 180       Subtract 118 from both sides

C + 118 - 118 = 180 - 118

C = 62

C + 57 = B          C and A are remote interior angles.  They equal the exterior angles that are not supplementary to B.

62 + 57 = B

B = 119

Help ASAP!!! 3/8 of the seventh grade students were taking Advanced math at the beginning of the year, but Seven dropped out by
Rashid [163]

Answer:

There are 392 students in the seventh grade.

Step-by-step explanation:

Let us assume that there are x number of students in the seventh grade.

Now, 3/8 of the seventh grade students were taking Advanced math at the beginning of the year, but seven dropped out by the end of the year.

So, after the end of the year there were (\frac{3}{8}x - 7) number of students taking advanced math.

So, as per given condition, (\frac{3}{8}x - 7) = 140

⇒ \frac{3}{8}x = 147

⇒ x = 392

Therefore, there are 392 students in the seventh grade. (Answer)

Which points are solutions??
IRINA_888 [86]
A, C and E all work in the equations. In order for them to work, you must use the ordered pair in each of the three situations. Below is the work for all of the correct answers. 

Ordered Pair A : (1, -1)
y < x + 1
-1 < 1 + 1
-1 < 1 (TRUE)

y < 4
-1 < 4 (TRUE)

x < 6 
1 < 6 (TRUE)

Ordered Pair C : (4, 2)
y < x + 1
2 < 4 + 1
2 < 5 (TRUE)

y < 4
2 < 4 (TRUE)

x < 6 
5 < 6 (TRUE)

Ordered Pair E : (4, -2)
y < x + 1
-2 < 4 + 1
-2 < 5 (TRUE)

y < 4
-2 < 4 (TRUE)

x < 6 
4 < 6 (TRUE)

If I understand the question:

(1/2) + (9/10) =

(5/10) + (9/10) = (14/10)

(14/10) is 1 and 4/10

The field is 1 and 4/10 mile long.

Twelve skateboards have 48 wheels what is the value of the ratio of skateboards wheel in simplest form
kirill115 [55]

The value of the ratio of skateboards wheel in its simplest form is <u>1:4</u>.

<h3>What is the ratio?</h3>

The ratio refers to the numerical relationship between two variables.

Ratios show the quantity of one variable contained in another.

Ratios are expressed in fractions, decimals, or percentages.  They can also be written using the ratio symbol (:).

The total number of skateboards = 12

The total number of wheels = 48

The ratio value of skateboards wheels = 48:12

= 4:1 or 1:4

Thus, we can conclude that for every skateboard, there must be 4 wheels, given their ratio values.
