Answer:
(-11)/5
Step-by-step explanation:
Simplify the following:
4/5 - 3
Put 4/5 - 3 over the common denominator 5. 4/5 - 3 = 4/5 + (5 (-3))/5:
4/5 + (5 (-3))/5
5 (-3) = -15:
4/5 + (-15)/5
4/5 - 15/5 = (4 - 15)/5:
(4 - 15)/5
4 - 15 = -(15 - 4):
(-(15 - 4))/5
| 1 | 5
- | | 4
| 1 | 1:
Answer: (-11)/5
An increase is adding, not multiplying. they meant that 5 times a number is 500% of something. it would be a 400% increase as one plus four is five.
Length of the cube = 7
Working:
Cube root of 343 =7
(or)
7^3=7*7*7=343
Answer:
Step-by-step explanation:
B + 87 +78 +66 = 360
B = 129 °
the angle next to B then is
180 = 129 + b '
51 ° = b '
A + 61 + b ' = 180
A = 68 °
Answer:
y = 2x - 3
Step-by-step explanation:
Slope intercept equation of a line:
y = mx + b
(0, -3) is the y-intercept, so b = -3
We have
y = mx - 3
Now we use the two points to find the slope.
slope = m = (-3 - 5)/(0 - 4) = -8/(-4) = 2
y = 2x - 3
