Answer:
BCG =65
Step-by-step explanation:
DCG + GCB = DCB
We know BCG = 31x+3 and GCD = 12x+2 and BCD = 91
Substituting these in
12x+2 + 31x+3 = 91
Combine like terms
43x +5 = 91
Subtract 5 from each side
43x+5-5 = 91-5
43x = 86
Divide by 43
43x/43= 86/43
x=2
BCG = 31x+3
=31(2)+3
=62+3
=65
Answer:
the number of silver medals won by Brazil is 14
Step-by-step explanation:
The computation of the number of silver medals won by Brazil is shown below:
Given that
Total number of gold and silver medal wons by Brazil was 35
And, the ratio of number of gold medals to the number of silver medals be 3 : 2
Based on the above information
The number of silver medals won would be
= 35 × 2 ÷ (3 + 2)
= 35 × 2 ÷ 5
= 14
hence, the number of silver medals won by Brazil is 14
A=+ or - 5 bc -5x-5 or 5x5 equals to 25
Answer:
He has driven 16 miles so far
Step-by-step explanation:
The unknown in your equation is the total length of Trey's drive, which we will call "x".
From the problem statement, you know that 12 is three-fourths of x so set up the following equation and solve for "x":
3/4(x) = 12
multiply both sides of the equation by 4/3 to isolate "x":
(4/3)(3/4)(x) = (12)(4/3)
therefore
x = (12)(4)/(3) = 16
Answer:
48
Step-by-step explanation:
Given,
x = - 1
y = 2
To find : The value of 3x - 4 ⋅ xy² ?
Substitute the given values of x and y in the expression 3x - 4 ⋅ xy².
3x - 4 ⋅ xy²
= 3 ( - 1 ) - 4 ⋅ ( - 1 ) ( 2 )²
= - 3 - 4 ⋅ - 1 ( 4 )
= - 12 ⋅ - 4
= 48
Note : -
When a negative number gets multiplied with a negative, the resulted number is a positive number.
