Ok I will add u to if you can help me with my test
We know that pupils are students
Students = S
boys = B
Teachers = T
So....
S = 8T
Boys = 3G
T = B - 70
Since there is 8x students than teachers, I did Boys = 6x and girls = 2x
I'm going to use this next: S = 8T
8x = 8(B -70)
8x = 8(6x - 70)
8x = 4x - 560
x = 14
We know there is 8x students, so there are 112 students and we know that there is 1/8 of teachers, so there are 14 teachers.
Answer = 126.
Ok so first you want to mutiply 5 and 2j which gets you 10j then 5 x 3 which equals 15 then you mutiply 5 and j which gets you 5j then you add like terms which are the two j’s and that will get you 15j + 15
ANSWER:
310 cm^2 (Don't ever forget the units) for the full surface area
STEP BY STEP:
I'll give you the area of the full thing.
First we will get the little square on the one side:
5 x 4 = 20
We got one side out of 8 sides.
Side 2:
10 - 5 = 5
5 x 4 = 20
Side 3:
5 x 4 = 20
Side 4:
5 x 4 = 20
Side 5:
5 + 5 = 10
10 x 4 = 40
Side 6:
5 + 5 = 10
10 x 4 = 40
Side 7:
10 - 5 = 5
5 x 5 = 25
5 x 5 = 25
5 x 5 = 25
25 + 25 + 25 = 75
Side 8:
10 - 5 = 5
5 x 5 = 25
5 x 5 = 25
5 x 5 = 25
25 + 25 + 25 = 75
ADD ALL SIDES TOGETHER:
75 + 75+ 40 + 40 + 20 + 20 + 20 + 20 = 310
Answer:
y=4x+5
Step-by-step explanation:
From the formula y=mx+c,
m=gradient
=4
c=point on the y-axis
=5
Therefore, y=4x+5
