*triple phytagoras*
first triangle h = second triangle h = 24 in
x = 7 (triple phytagoras)
The distributive property....u r basically multiplying the number outside of the parenthesis by everything inside the parenthesis...this gets rid of the parenthesis.
3(-4x + 8)...distribute the 3 thru the parenthesis
(3 * -4x) + (3 * 8) ...take that 3 and multiply it by every number in the parenthesis..to get rid of the parenthesis
-12x + 24 <===
4(x - 6y) =
(4 * x) - (4 * 6y) =
4x - 24y <===
6(5 - q) =
(6 * 5) - (6 * q) =
30 - 6q <===
1/2(c - 8) =
(1/2 * c) - (1/2 * 8) =
1/2c - 4 <===
-3(5 - b) =
(-3 * 5) - (-3 * b) =
-15 - (-3b) =
-15 + 3b <===
(d + 2)(-7)....re-arrange
-7(d + 2) =
(-7 * d) + (-7 * 2) =
-7d + (-14) =
-7d - 14 <===
First you do 200 miles divided by 25 km. It is 8. This means you need 8 gallons for the whole trip. 8 times 6dollars is 48 dollars. You will need to pay 48 dollars in gas prices.
Answer: 7.4a+b
1. distribute
=5a+(2.4)(a)+(2.4)(0.5b)+−0.2b
=5a+2.4a+1.2b+−0.2b
2. combine like terms
=5a+2.4a+1.2b+−0.2b
=(5a+2.4a)+(1.2b+−0.2b)
=7.4a+b
441 to the nearest ten is 440
345 to the nearest ten is 350
The sum is;
440 + 350 = 790
