Answer:
3) x=4 4)x = 9 5) x=5
Step-by-step explanation:
3) first you have to find the inside of the angle. A straight line = 180*
180-(19x+3) = 177-19x
Than you add all the angles up to equal 180.
(177 - 19x) + (11x-2) + (9x+1) = 180
if you simplify this x = 4. You can check your answer by subbing in for x.
4)first you have to find the inside of the angle. A straight line = 180*
180- (17x-23) = 203-17x
Than add the sides up to equal 180. keep in mind there are 2 of the same angles.
(203-17x)+(7x+2)(2) = 180
Simplify
x=9
5) 180-151=29* this is the inner angle.
(11x-1)+(20x-3)+29=180
31x+25=180
x=5
Answer:
let this happens after t hours
so
80t + 60t = 392
140 t = 392
t = 392/140
=2.8 hours
Answer:
70 + 95 = 5(14 + 19)
Step-by-step explanation:
To factor the expression, 70 + 95, using the GCF, take the following steps:
✔️Find the prime factors of each number:
Prime factors of 70 = 2 × 5 × 7
Prime factors of 95 = 5 × 19
Multiply the factors that both numbers have in common to get the GCF.
This, both number have only one factor in common which is 5.
Therefore, the GCF of 70 and 95 is 5.
✔️Factoring the experession given using the GCF, we have:
70 + 95 = 5(14 + 19)
Suppose you are given the two functions f (x) = 2x + 3 and g(x) = –x2 + 5. Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))".
