Answer:
x y
0.75 6
1.5 12
3 24
Step-by-step explanation:
Proportional relationship between x and y is often written as y = kx.
In the table,
x = 0.75 and y = 6
x = 1.5 and y is unknown.
Since then
When multiplying 12 by 2, you get 24 and when multiplying 1.5 by 2, you get 3, so the last row is x = 3 and y = 24.
The answer is 66.75
I would suggest multiplying 2 in (2x+1) by 2 5/8 first, then multipling 4 by 2 5/8. This will garner you 10 and 5.25. Distribute the 9 into the (). You'll then get 10.5+47.25+9
Add and you will get 66.75
Answer:
1: 24 girls
2: 640
3: 300
4: 3/10
5: 42
Step-by-step explanation:
1: 2/5 × 40
80÷ 5
16
girls = 40- 16
= 24
2: 1/3 × 960
960 ÷3
= 320
Left = 960 - 320
= 640
3: 3/8 × 480
1440 ÷ 8
= 180.
Left = 480 - 180
= 300
4: 2/5 × 3/4
= 6/20
= 3/10
5: 2/5 × x = 18
2x = 28 × 5
2x = 140
x = 70
70 - 28
= 42
The answer would be A because u have to distribute the negative into the equation
The system of equation has no solution.Because the variables in the given equation got canceled during substation.
<h3>How can we determine the solution to an equation?</h3>
We do the identical actions on both sides to ensure that both expressions remain equal. Solving equations entails determining the values of the variables involved for which the equation is valid.
The given equation is;
Equation 1;
Equation 2;
From the equation 1 find the value of the y and put in the equation 2 as;
From the above equation, it is observed that the variables in the equation got canceled.
Hence, the system of equation has no solution.
