Answer:
(x -7)(7x +4)
Step-by-step explanation:
The term -45x can be rewritten using factors of (7)(-28) that have a total of -45. Those factors would be ...
(7)(-28) = (4)(-49)
7x^2 +4x -49x -28 = x(7x +4) -7(7x +4) = (x -7)(7x +4)

GivenR is the midpoint of SQ and PTTo proveΔPQR ≅ ΔTSRSolutionR is the midpoint of SQ
SR = 1/2SQ and RQ = 1/2SQ ⇒ SR ≅ RQR is the midpoint of PT
PR = 1/2PT and RT = 1/2PT ⇒ PR ≅ RTSQ and PT intersect at point R ⇒
∠PRQ ≅ ∠TRS as vertical anglesTriangles PQR and TSR have two sides and the included angle congruent, therefore:

Maria's Grocery Store buys grapefruit at a cost
of 5 for a dollar. They sell them at a price of 5
for three dollars. How many must they sell in
order to make a profit of ten dollars?
Answer: 25 grapefruits
Step-by-step explanation:
They buy grapefruit at a price of 5 per dollar. This means that the price per grapefruit is:
= 1 / 5
= $0.20 per grapefruit.
They then sell at a price of 5 per $3. The selling price per grapefruit is:
= 3 / 5
= $0.60
The profit per grapefruit is:
= 0.60 - 0.20
= $0.40
In order to make a profit of $10, they should sell:
= 10 / 0.4
= 25 grapefruits

Angelica has a babysitting business. She babysat on Friday night and made $60
plus a 20% tip. How much was the tip? How much was the total?
Answer:
The tip was $12. The total was $72.
Step-by-step explanation:
First, we need to find how much the tip is. 20%=1/5 of the amount of money. If you divide 60 by 5, you get 12. This means that the tip was 12 dollars. If you add 60+12 you get 72 meaning that the total amount of money Angelica got was $72.

Answer:
312.5 t⁴
Step-by-step explanation:
25*t⁻⁴ = (5²) / t⁴ (1)
5⁻³*10*t⁻⁸ = 5⁻³*2*5¹ / t⁸ (2)
(1)/(2): ((5²) / t⁴) / ((5⁻²*2) / t⁸) = 5⁴ * t⁴ / 2 = 625 t⁴ / 2 = 312.5 t⁴

find the total surface area for this cuboid
Answer:
24cm
Step-by-step explanation:
surface= Ixb
= 6x4
= 24cm
Answer:
148cm(squared)
Step-by-step explanation:
5 x 6 = 30
5 x 4 = 20
6 x 4 = 24
30 + 24 + 20 = 74cm
74cm x 2 = 148cm(s)
The ratio of boys to girls in a group is 7:3. If there are 40 more boys than girls, work out how many girls there are
Answer:
Odadasdsadasadad
Step-by-step explanation:
Answer:

Step-by-step explanation:
Tanner is picking three varieties of apples at an orchard: Gala, Fuji, and Jazz. Each type of apple has a different cost per pound. He knows that 1 pound of each apple variety would cost a total of $5.16, and that the cost per pound of Jazz apples is the same as the combined cost per pound of the Gala and Fuji apples. Tanner picks 12 pounds of apples, including 3 pounds of Gala and 5 pounds of Fuji, for a total cost of $21.24.
If g represents the cost per pound of Gala apples, f the cost per pound of Fuji apples, and j the cost per pound of Jazz apples, which system of equations represents this situation?
Answer:
2g + 2f = 5.16
7g + 9f = 21.24
Step-by-step explanation:
Let
Gala = g ; Fuji = f ; jazz = j
g + f + j = 5.16 - - - (1)
j = g + f - - - (2)
From (1):
g + f + g + f = 5.16
2g + 2f = 5.16 - - - (3)
Total pound picked by Tanner = 12
3 Pounds of g ; 5 pounds of f
j = 12 - (5 +3) = 4 pounds
3g + 5f + 4j = 21.24 - - - (4)
3g + 5f + 4(g + f) = 21.24
3g + 5f + 4g + 4f = 21.24
7g + 9f = 21.24 - - - - - (5)
