HELP MEEEEEEEEEEEEEEEEE PLZ

Mathematics
1 answer:
Hitman42 [59]3 years ago
6 0

Answer:

x = 32, ∠A = 132

Step-by-step explanation:

A and B are equal. Set both equations equal to each other.

5x - 18 = 3x + 42

Add 18 to both sides and subtract 3x from both sides.

2x = 60

Divide both sides by 2.

x = 30

Now plug x back in to solve for angle A.

5(30) - 18 = 132

For the scatter plot on homework:

a) The relationship is that the test score will increase, if the time spent on homework increases.

b) The function is y=8x+40, and what we need to see is what the score will be if someone puts in 3 hours of homework, x=3 in this because it means the time spent on homework:

y=8(3)+40

y=24+40

y=64

c) The score would be 40% if no time was spent doing homework.

For the scatter plot on the rides:

a) y = -7/5x + 17.8

b) Anika worked 17.8 hours on Day 0

c) Decreased by 7/5 in a day.

Hope this helps, have a BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)

The combined land area of the countries A and B is 178,973 square kilometers. Country A is larger by 373 square kilometers. Dete
ruslelena [56]
X=area of the country A
y=area of the country B
we saggest this system of equations:
x+y=178,973
x=y+373
we solve this system of equations by substitution method.
(y+373)+y=178,973
2y=178,973-373
2y=178600
y=178,600/2=89,300

x=y+373
x=89300+373=89,673

answer:
area of the country A=89,673 Km²
area of the country B=89,300 Km²

To check
The combined land area of the countries A and B is =89,673 Km²+89,300 Km²=178,973 Km²
Country A (89,673 Km²) is 373 Km² more larger than country B (89,300 Km²).
89,673 Km²=89,300 Km²+373 Km²
