Answer:
Step-by-step explanation:
small=s, s=3.99
large=l, l=19.20
10s+8l=192.20
20s+l=99
we can see that in the second equation, 20s+l=99
l=99-20s
lets replace l in the first equation
10s+8(99-20s)=192.20
10s+792-160s=192.20
-150s=-792+192.20
150s=599.80
s=3.99
l=99-20(3.99)=99-79.80=19.20
Answer:
4
Step-by-step explanation:
ΔABC is congruent with ΔDEF. That means the corresponding sides are congruent.
Look at the order of the letters. EF are the last two letters of ΔDEF. So this corresponds with the last two letters of ΔABC. Therefore, EF ≅ BC.
EF ≅ BC
x² + 8x = 48
x² + 8x − 48 = 0
(x + 12) (x − 4) = 0
x = -12 or 4
Since x can't be negative, x = 4.
It’s 121 feet bc 484 divided by 4 (because there’s 4 sides to a fenced area) is 121
Answer:
d. -4
Step-by-step explanation:
- 4p – 12 = 8 + 4p + 5p
- 4p – 12 = 8 + 9p
- 4p – 9p = 8 + 12
- – 5p = 20
- p = 20 ÷ (– 5)
- p = – 4
An equation of a line can be written as :
where m is the slope. So we can say that
.
To fine the value of p , we use the coordinates of the point (0,-4). Can you find the value of p ?
