The perimeter of a triangle is 122 centimeters. If two sides are equally long and the third side is 8 centimeters longer than the others, find the lengths of the three sides.
Answer:
2 sides are 38cm long
The third is 46cm long
Step-by-step explanation:
We can use the following equation to solve
[tex]122 =x + x + (x + 8)[/tex]
Reduce
[tex]122 = 3x + 8[/tex]
114÷3 = x
x = 38
We then add 38 and 8 because the 3rd side is 8cm longer

Step-by-step explanation:
If f(x) is a linear function ,f(-1)=-3 , and f(4)=-5 , find an equation for f(x)
Answer:
f(x) = -²/₅ x - ¹⁷/₅Step-by-step explanation:
The equation of the linear function: f(x) = mx + b
f(-1) = -3 ⇒ -3 = m(-1) + b ⇒ m = b + 3
f(4)=-5 ⇒ -5 = m×4 + b
-5 = 4(b+3) + b
-5 = 4b + 12 + b
5b = -5 - 12
b = -¹⁷/₅
m = -¹⁷/₅ + 3 = -¹⁷/₅ + ¹⁵/₅ = -²/₅
Therefore the function:
f(x) = -²/₅ x - ¹⁷/₅How do you write 24/32 in simplest form?
Answer:
3/4
Step-by-step explanation:
To find 24/32 in its simplest form, you need to find the biggest common factor.
24: 1, 2, 3, 4, 6, 8, 12, 24
32: 1, 2, 4, 8, 16, 32
For these two numbers, it's 8. Divided 24 and 32 by 8.

5. The internal dimension of a tank are 14m, 8m and 5m. How much water can be
filled in it. Write the answer in litre. (1m = 100 litre)
Answer:
560,000L
Step-by-step explanation:
Given data
L=14m
W=8m
H=5m
Volume= L*W*H
Volume= 14*8*5
Volume= 560 m^3
1m^3 = 1000L
560m^3 = x
cross multiply
x= 560*1000
x= 560,000L
Hence the volume is 560,000L

Triangle ABC is a right triangle.
m∠A=5x°
m∠B=(3x−4)°
m∠C=90°
What is the value of x?
Answer:
x = 47/4
Step-by-step explanation:
The acute angles of a right triangle are complementary, i.e. their sum is 90
So, 5x + 3x - 4 = 90
8x = 94
x = 94/8 = 47/4
Answer: The value of X is 47/4
Step-by-step explanation:
find the value of x
x=
Answer:
Step-by-step explanation:
x + 115 + 95 + 70 = 360 ( being sum of angles of quadrilateral )
x = 360 - 115 - 95 - 70
x = 80
