Step-by-step explanation:
2 ( 8 - 3c) = 4c - 34
16 - 6c = 4c - 34
6c + 4c = 16 + 34
10c = 50
c = 50/ 10
therefore c = 5
Hope it will help :)
Answer:
a) 450. b) 1:1.25 c) 32 rooms
Step-by-step explanation:
1. 100*4.5 = 450
2. 16:20 divide by 4 -> 4:5 (simplifies to 1:1.25)
3. 64/2 = 32 rooms needed. They have 16.
Sorry if answers are wrong, the picture quality is really poor for me.
4x-10 and 7x-8 are supplementary angles and thus add up to 180 degrees.
Thus, 11x - 18 = 180 degrees.
Combining like terms, 11x = 198, and x = 18.
The two supplementary angles are 4(18)-10 and 7(18)-8, or 62 and 118 degrees.
(1.) 35-3m
m= 4
35-3m
= 35-3(4)
= 35-12 (do the multiple/division first before doing the addition/subtraction)
= 23
C. 23
(2.) 1 + x ÷ 5
x = 80
1 + x ÷ 5
= 1+80÷5
= 1+16
= 17
(3.) mx-y
m=5, x=3, and y=8
mx-y
= 5(3)-8
= 15-8
= 7
(4.) 3a+15+bc−6
a=7, b=3, and c=15
3a+15+bc-6
= 3(7)+15+3(15)-6
= 21+15+45-6
= 75
Answer:
slope = 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
8x - 8y = 16 ( subtract 8x from both sides )
- 8y = - 8x + 16 ( divide all terms by - 8 )
y = x - 2 ← in slope- intercept form
with slope m = 1
