Answer:
<em>188 yards </em>
Step-by-step explanation:
Given
Length of one balloon = 12 feet
Since 1 foot = 1/3 yards
12 feet = x
Cross multiply
1 * x = 1/3 * 12
x = 12/3
x = 4 yards
Hence one balloon will be 4 yards long.
If one balloon = 4 yards long
47 balloons = y
Cross multiply;
1 * y = 4 * 47
<em>y = 188yards</em>
<em>Therefore Cesar will need 188 yards of string for 47 ballooons</em>

Answer: (C)A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10.
Let Jack's speed be x. Bob's is then x + 4.
Jacks time for the 1000 km is 1000/x.
Bob's is 1000/(x+4) + 1/2 (the 1/2 being the 30 minutes he was delayed).
They tied so their times were equal. 1000/x = 1000/(x+4) + 1/2.
We multiply by x(x+4) and get 1000(x+4) = 1000x + x(x+4)/2.
Simplifying, we get x^2 + 4x - 8000 = 0. x = [- 4 + √(16 +32000)]/2 = √8004 -2, Jack's speed.
Bob's will be √8004 +2.
This seems way too fast! But I don't see any mistake<span>

Answer:
y=-3x-4
Step-by-step explanation:
To put this in slope-intercept first put it in slope-point then simplify. So in slope-point, this would be y - 5 = -3 (x + 3), then solve
First, distribute the -3
y-5 = -3x-9
Then, move the five to the right side by adding it to both sides
y=-3x-4, therefore the slope is -3 and the intercept is -4.
