Answers

Answer 1

Answer:

m = 111.5

j = 35.5

I really hope this is right ;(

Step-by-step explanation:

m = 3j + 5


j + 3j + 5 = 147
4j + 5 = 147
4j = 142
142 ÷ 4 = 35.5

So j = 35.5

3(35.5) + 5 = 111.5

Answer 2
3(35.5) + 5 = the answer is 111.5

What are negative numbers?

In the real number system, a negative number is a number that is less than zero.

Given are two negative numbers, -4 and -4

Adding two negative numbers is: you're just adding two "negative" arrows, so it's just like "regular" addition, but in the opposite direction. For instance, 4 + 6 = 10, and −4 − 6 = −4 + (−6) = −10.

Therefore, -4 + (-4) = -4-4 = -8

Hence, -4 + (-4) = -4-4 = -8

Answer:

76°

Step-by-step explanation:

Use the Exterior Angle Property. The Exterior Angle Property states that an exterior angle of a triangle is equal to the sum of it's two opposite non adjacent interior angles.

In this case, set the exterior angle equal to the sum of the two given interior angle measurements:

(c) + (c - 26) = c + 50

First, simplify, combine like terms. Like terms are terms that share the same amount of the same variable:

c + c - 26 = c + 50

(2c) - 26 = c + 50

Next, isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Subtract c and add 26 to both sides of the equation:

2c (-c) - 26 (+26) = c (-c) + 50 (+26)

2c - c = 50 + 26

c = 76

76° is your answer.

Lyla's kite spool had 80 yards of string. She let out 40 feet. Then the kite continued to rise, using another 12 yards of string. How many feet of string were left on the spool?

164 feet
212 feet
76 feet
52 feet

Answers

Answer: 164


80 yards can be converted into 240 feet then you can subtract 40ft from 240ft and get 200 ft then you convert 12 yards into 36 ft and now you need to subtract 36 form 200 ft and get 146 ft.

Hope this helped ;)

The required answer is 164 feet of string left on the spool from conversion from yards to feet.

In other words, the required answer is 164 feet.

To determine how many feet of string were left on the spool, we need to convert the given measurements to a consistent unit (either yards or feet) and then subtract the amount of string used from the total length. Let's go through the steps:

Step 1: Convert the measurements to a consistent unit.

Given:

80 yards of string

40 feet of string

12 yards of string

Since we want to work with feet, let's convert the yards to feet. We know that 1 yard is equal to 3 feet, so:

80 yards = 80 x 3 = 240 feet

12 yards = 12 x 3 = 36 feet

Now we have:

240 feet of string

40 feet of string

36 feet of string

Step 2: Calculate the total length of string used.

To find the total length of string used, we add up the amounts:

40 feet + 36 feet = 76 feet

Step 3: Subtract the total length of string used from the initial total length.

240 feet - 76 feet = 164 feet

Therefore, there were 164 feet of string left on the spool from conversion from yards to feet

The answer is 164 feet.

Looking at the Venn diagram

5 students - Jack, Frank, Juanita, Angel and Ta'Ron have visited Wack-o-World

3 students - Juanita, Angel and Ta'Ron have visited The Capital

The only table matching this data is table A

I will give you the interpretations of the names inside the intersecting of the three circles

The intersection of the 3 circles has 2 names, Angel and Ta'Ron. This means they have visited all three places

The other interpretations are
Jack and Frank have visited only Wacck-o-World

JoAnn and Joe have visited only Gator Land

That's because these names do not occur at the intersection of any of the circles
