we know that

Perimeter of a triangle is equal to

P=a+b+c

where

a,b and c are the length sides of the triangle

<u>Find the perimeter of the triangles</u>

<u>Triangle N 1</u>

P=(x-2)+(x)+(3x+1)-------> P=5x-1

<u>Triangle N 2</u>

P=(2x-5)+(x+4)+(6x-7)------> P=9x-8

equate the perimeters

5x-1=9x-8--------> 9x-5x=-1+8-------> 4x=7

x=7/4------> x=1.75

therefore

the answer is

x=1.75

An archer hits a bullseye 64% of the time. What is the probability the archer hits
Brums [2.3K]

Answer:

C. 0.077

Step-by-step explanation:

Use binomial probability.

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

n = 10, r = 4, p = 0.64, q = 0.36.

P = ₁₀C₄ (0.64)⁴ (0.36)⁶

P = 210 (0.64)⁴ (0.36)⁶

P = 0.077

13 – 6 + 4 i need help because there is a big math test coming up at my school and i need to study for it.
qwelly [4]
First you would follow the Order Of Operations:
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction 
Second step: You will add 6 and 4 together since addition came before subtraction in the Order Of Operations.You would get 10.
Your equation should now look like: 13-10.
Last step: You would subtract 10 from 13 since there are no other numbers
Your answer should then be: 3
HOPE THIS HELPS! ^_^
