Answer:
96
Step-by-step explanation:
The ratio of the measure of sides of a triangle are 8:15:17
The perimeter is 480
8x + 15x + 17x= 480
40x= 480
x = 480/40
x = 12
Therefore the measure of the shortest side of the triangle can be calculated as follows
8x
8×12
= 96
Answer:
550 miles per hour
Step-by-step explanation:
The answer is 1 and 2/3. 5/3 means 5 divided by 3. 5 goes into 3 once so the whole number is one. There is then 2 left so you are left with 2/3. 2 doesn't go into 3 so you leave it like that. This makes the answer 1 and 2/3 because 1 is the whole number and 2/3 is the unit fraction.
Answer:
x = 50
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Therefore, add together the expressions for all 4 angles, equal to 360, and solve for x:
(2x + 15) + (3x - 20) + x + (x + 15) = 360
Gather like terms: 2x + 3x + x + x + 15 - 20 + 15 = 360
Combine like terms: 7x + 10 = 360
Subtract 10 from both sides: 7x = 350
Divide both sides by 7: x = 50
Answer:
Jill did not change the symbol of inequality from minor (< ) to major (>) in the Step 4
Step-by-step explanation:
we have

step 1
Multiply by 12 both sides



step 2
Group terms

step 3
Combine like terms

step 4
Divide by -7 both sides
Remember that when you multiply an inequality by -1 the < symbol changes to the > symbol
so
Jill did not change the symbol of inequality from minor (< ) to major (>) in the Step 4
