Answer:
x = 3
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the triangle , then
15x + 5 + 22x + 4 = 120
37x + 9 = 120 ( subtract 9 from both sides )
37x = 111 ( divide both sides by 37 )
x = 3
Answer:
$6.22
Step-by-step explanation:
Given;
Total number of coins N = 50
Number of pennies p = 14% of N = 0.14 × 50 = 7
Number of dimes d = 32% of N = 0.32×50 = 16
Number of nickels n = 4 + number of pennies = 4+p
n = 4+7 = 11
Number of quarters q;
N = p+d+n+q
q = N - (p+d+n)
q = 50-(7+16+11)
q = 16
1 Penny = 1 cent = $0.01
1 Nickel = 5 cent = $0.05
1 dime = 10 cents = $0.10
1 quarter = 25 cents = $0.25
Total amount in the bag is;
C = 0.01p + 0.05n + 0.10d +0.25q
Substituting the values;
C = 0.01(7) + 0.05(11) + 0.10(16) + 0.25(16)
C = $6.22
The bag contains $6.22
Answer:
3(x+6)=3x+18 = infinite
x-7=-7+x = infinite
5(x-3)=15+5x = no solution
<u>Answer:</u>
A. 10
B. 18
C. 8
D. 16
<u>Step-by-step explanation:</u>
We are given a number of incomplete fractions and we are to find the missing numerator in each one of these.
To find the missing numerator or denominator, we multiply the numerator and the denominator by the same number to get an equivalent fraction.
A. 
Here the denominator is multiplied by 2 so the denominator will also be multiplied by 2 to get 10.
B. 
Numerator is multiplied by 9.
C. 
Numerator is multiplied by 4.
D. 
Numerator is multiplied by 4.
1500 km. because 600 x 2 (2 for hours) = 1,200 plus half an hour being 300 km = 1,500.
