Answer:
35 2-point questions, and 15 5-point questions
Assume x 2-points question, so 50-x 5-points question
Total no of points: 2*x+5*(50-x)=145 points
2x+250-5x=145
-3x=-105
x=-105/-3=35 2-points questions
Remaining 50-35=15 5-points questions
ok so i really hope this helped and if it didn't then sorry
Answer:
x = 10
Step-by-step explanation:
=> 4x + 1 + 2x = 61
=> 6x = 61 - 1
=> 6x = 60
=> x = 60/6
=> x = 10
<u>Hence</u><u> </u><u>the</u><u> value</u><u> of</u><u> x</u><u> </u><u>is</u><u> </u><u>1</u><u>0</u><u> </u><u>.</u>
1.10 = x + y
x = 1 + y
subtract 1
.10
x = y
.10
the answer is .10
Answer:
A. a = $3, p = $6
Step-by-step explanation:
Let the cost of a bucket of apple=a
Let the cost of a bucket of peaches=p
6 buckets of apples and 4 buckets of peaches costs $42.
8 buckets of apples and 2 buckets of peaches costs $36.
- 8a+2p=36 (Multiply by 2 to make the coefficient of p 4)
We solve the two resulting equations simultaneously
6a+4p=42
16a+4p=72
Subtract
-10a=-30
Divide both sides by -10
a=$3
Next, we substitute a=$3 in any of the equation to solve for p
6a+4p=42
6(3)+4p=42
4p=42-6(3)
4p=42-18
4p=24
Divide both sides by 4
p=$6
Therefore, a bucket of apple costs $3 and a bucket of peaches costs $6.
