Answer is C :)
Already has same denominator, so 7+5= 12
12/9 is improper fraction so you have to give your answer as a mixed fraction:)

C. 1 1/3
7/9 + 5/9 = 12/9
12/9 = 1 3/9 = 1 1/3

Four - fifths of z added to six equals eight

ella [17]

The four-fifths of a number, in this case, z is four times the number divided by z. That is 4z/5. When we add six to the product and equate the expression to 8, we get,
4z/5 = 8
The value of z from the equation is 10.

For f(x)= 4x+1 and g(x) = x squared -5 , find (f-g)(x)

makvit [3.9K]

Hope i am not wrong
f(x)=4x+1
g(x)=x^2-5

(f-g)(x)=f(x)-g(x)
(f-g)(x) =4x+1-x^2+5

-(x^2-6-4x)
solve it for x

PLSS help me with this question?

Xelga [282]

Answer:

Part a) By alternate interior angles

Part b) By vertical angles

Part c) By AAA (Angle-Angle-Angle) Similarity Theorem

Part d) Triangles ABC and CDE are similar

Part e) $b=\frac{2DE}{3}$ or $b=\frac{15}{AC}$

Step-by-step explanation:

Part a)

we know that

If AB is parallel to DE

then

m<1=m<4 ------> by alternate interior angles

Part b)

we know that

m<5=m<6 -------> by vertical angles

Part c) we know that

The two triangles are similar by AAA (Angle-Angle-Angle) Similarity Theorem ------> The three corresponding angles are equal

m<1=m<4

m<5=m<6

m<3=m<2

Part d) we know that

If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

therefore

Triangles ABC and CDE are similar

Part e) Find the length side of b

Remember that

If two figures are similar, then the ratio of its corresponding sides is equal

$\frac{AB}{DE}=\frac{BC}{DC}=\frac{AC}{CE}$

substitute the values

$\frac{3}{DE}=\frac{2}{b}=\frac{AC}{7.5}$

$b=\frac{2DE}{3}$

$b=\frac{2*7.5}{AC}=\frac{15}{AC}$

A SUV drove 200 miles on 9 gallons of gas. A truck drove 280 miles on 10 gallons of gas. Find both unit rates for both vehicles.

lawyer [7]

Answer:

Suv= About 22 miles

Truck= 28 miles

Step-by-step explanation:

To find the unit rate of both vehicles, divide the number by how many gallons of gas to see how many miles both vehicles drive on 1 gallon.
