Answer:
6
Step-by-step explanation:
18x−(8x−7)=67
Step 1: Simplify both sides of the equation.
18x−(8x−7)=67
18x+−1(8x−7)=67(Distribute the Negative Sign)
18x+−1(8x)+(−1)(−7)=67
18x+−8x+7=67
(18x+−8x)+(7)=67(Combine Like Terms)
10x+7=67
10x+7=67
Step 2: Subtract 7 from both sides.
10x+7−7=67−7
10x=60
Step 3: Divide both sides by 10.
Answer:
Options A ,B and E
Step-by-step explanation:
Here 2/5 is less then one then all sides are gonna 2/5 of initial length hence reduction occur.
Angles are not gonna affected because it is like zoom in.
Center of dilation can be anywhere as point Q is not specified in question thus it is wrong.
Yeah base of rectangle is reduced by a factor of 2/5.
Answer:
Step-by-step explanation:
y = 0.2x + 17......the slope is 0.2 (or 1/5)....in y = mx + b form, the slope can be found in the m position
(x,18).....y = 18 (25,y).....x = 25
y = 0.2x + 17 y = 0.2x + 17
18 = 0.2x + 17 y = 0.2(25) + 17
18 - 17 = 0.2x y = 5 + 17
1 = 0.2x y = 22..........(25,22)
1 / 0.2 = x
5 = x.................(5,18)
Answer:
Part a) 
Part b) 
Part c) 
Part d) 
Step-by-step explanation:
Part a) The difference of the squares of 2m and 7n.
we know that
The difference of the squares formula is equal to

substitute

Part b) The square of the difference of x and 8y
The formula of the square of the difference between two numbers is equal to

substitute

Part c) The tripled product of 6a and b^2
we have

Part d) The product of the sum of a and b and their difference
The expression is equal to

The expression represent the difference of the squares between a and b
so

56 reduced as a fraction is 56/100 or 14/25
