For a right triangle with legs legnth a and b and hyptonuse c
a²+b²=c²
ok, so side lengths (legs) re 5 and 6, find c or x (c=x=hypotonuse)
6²+5²=x²
36+25=x²
61=x²
sqrt both sides
√61=x
well, the equation would be a²+b²=c² or
This is a multi step problem. For this we do system of equations.
2.5x + 7y = 82.50
X+y = 24
To do the elimination method we have to make the y values equals to each other so we multiply the x+y=24 equation by 7
7x +7y = 168
-
2.5x + 7y = 82.50
———————————-
4.5x = 85.50
————————-
4.5. 4.5
X = 19

Answer:
$128
Step-by-step explanation:
1. We need to find how much 1 yard of material cost.
If needed, use a calculator*
120/75=1.6
2. Now we need to know how much 15 yards of material cost.
1.6 times 15=24
3. The buyer ordered an additional 90 yards. If we know how much 75 yards cost, and 15 yards, all you have to do is...
120+24=144
90 yards=$144
4. The additional cost is $144
(Note: the total cost would be $264 (120+144=264))
Answer:
2/3 or 2 over 3
Step-by-step explanation:
4 over three means 4 pieces out of 3. 4 pieces divided by 2 is 2 pieces.
