Answer:
28j + 21
step-by-step explanation:
(7) (2j+3+2j)
=(7*2j) + (7*3) + (7*2j)
=14j + 21 + 14j
=28j + 21
Answer:
C(x) = 12x + 1680
Slope = 12
Intercept = 1680
Step-by-step explanation:
Given that:
X1 = 60 chairs ; y1 = 2400
X2 = 260 chairs ; y2 = 4800
Obtain the slope ; m
m = y2 - y1 / x2 - x1
m = 4800 - 2400 / 260 - 60
m = 2400 / 200
m = 12
Using the point slope relation:
y - y1 = m(x - x1)
y - 2400 = 12(x - 60)
y - 2400 = 12x - 720
y = 12x - 720 + 2400
y = 12x + 1680
C(x) = 12x + 1680
From the general slope intercept equation :
y = mx + c
m = slope ; c = intercept
Hence,
C(x) = 12x + 1680
Slope = 12
Intercept = 1680
Answer:
3. x = 11.6
4. f = 2 g = 2
Step-by-step explanation:
3) (3x - 7) + (4x + 6) = 90 --> x = 11.6
4) 3f + 1 = 5f - 15 ---> f = 2
6g - 5 = 3f + 1
6g = 3(2) + 6 ---> g = 2
Answer:
The dimensions of the larger rectangle are 
of length by 
of width
Step-by-step explanation:
Let
x-----> the length of the larger rectangle
y-----> the width of the larger rectangle
we know that
------> by similar rectangles
-----> equation A
<u>Find the perimeter of the smaller rectangle</u>
<u>Find the perimeter of the larger rectangle</u>
Subtract the perimeter of the smaller rectangle from 100 cm of string
Remember that
------> 
------> equation B
substitute equation A in equation B
Find the value of x
The dimensions of the larger rectangle are of length by of width
