The measure of the 3 angles in a triangle are (4x) degrees,(3x-3) degrees, and (5x+3)degrees. Please write an equation, solve for x, and determine the measure of each angle. Please show work and thanks for helping

Answers

Answer 1

Answer: This is a good one!

So we know that a triangle's angles must add up to 180 degrees. Therefore, we can say that:

(3x - 3) + (5x + 3) + (4x) = 180.

This can be rewritten as 12x = 180.

Divide each side by 12 to get x alone, you get:

x = 15

Time to plug n' chug.

4x = 60, 3x - 3 = 42, 5x + 3 = 78

Boom!

14. teacher needs 70 lengths of string cut to 40 cm each. If balls of string are 10m longhow many balls will be needed.

Answers

70×40=2800cm which is the total amount of cm that the teacher needs

10m = 1000cm

$(2800)/(1000)$ = 2.8

there will be 3 balls of string

70×40=2800 cm, which would be the total amount of cm that the teacher needs for the balls.

10m = 1000cm

= 2.8

There will be 3 balls of string.

How do I help my child figure this out? What methods should she use? It is 4:02. What time was it 2 hours and 19 minutes ago?

Answers

subtract two hrs : 2:02 then subtract twenty minutes : 1:42 and then add 1; 1:43

You should tell your child to figure out how much time 2 hours and 19 minutes will be (2:19). What I'd do is take 2:19 and subtract that from 4:02. I'm pretty sure that this is correct. Hope this helps!

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

given that,

Joe's bathroom floor is 5 feet wide and 8 feet long. He will cover the floor with 3" square tiles.

so first find area

area=legnth times width

5=width

8=legnth

5 times 8=40

so, we have,

area=40

3 area times x number of tiles=40

divide both sides by 3

x=40/3

x=13 and 1/3

since you can't buy 1/3 tiile

round up

x=14

answer is 14 tiles does Joe need.

Can someone help me please!!!!!1.Grace and Allie are going to meet at the fountain near their houses.They both leave their houses at the same time. Allie passes Grace's house on her way to the fountain.
* Allie's walking rate is 2 meters per second.,* Grace's walking rate is 1.5 meters per second.
A-How many seconds will it take Allie to reach the fountain.
b-Suppose Grace's house is 90 meters from the fountain. Who will reach the fountain first,Allie or Grace explain why.

Answers

Well, if the fountain is 90 meters from the fountain, to find Allie's distance, simply divide 2 by 90.
90/2 = 45

It will take Allie about 45 seconds to reach the fountain.

Obviously, Allie will reach the fountain first because she is walking more meters per second.
