Answer: 1
Step-by-step explanation: can only be split evenly by one line.
Number of sodas sold = 130
Number of hot dogs sold = 65
Step-by-step explanation:
Given,
Combined number of sodas and hot dogs sold = 195
Let,
x represent the number of sodas sold
y represent the number of hot dogs sold
According to given statement;
x+y=195 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 3
Putting y=65 in Eqn 2
Number of sodas sold = 130
Number of hot dogs sold = 65

Step-by-step explanation:
If x is the mass of 30% copper alloy, and y is the mass of 65% copper alloy, then:
x + y = 80
0.30x + 0.65y = 0.51(80)
Solving the system of equations using substitution:
0.30x + 0.65(80 − x) = 0.51(80)
0.30x + 52 − 0.65x = 40.8
11.2 = 0.35x
x = 32
y = 80 − x
y = 48
The metalworker needs 32 kg of 30% copper alloy and 48 kg of 65% copper alloy.
The answer should be B if I am correct
Answer:
<h3>
41</h3>
Step-by-step explanation:
The consecutive integers are increasing by 1
x ← the smallest integer
x+1 ← the middle integer
x+1+1 = x+2 ← the largest integer
x + x+1 + x+2 = 120
3x + 3 = 120
÷3 ÷3
x + 1 = 40
-1 -1
x = 39
x+2 = 39 + 2 = 41
