I think of a number, multiply it by 4 then subtract 7. I get an answer of 2. What number was I thinking of?
13
36
15
1
I think of a number, multiply it by 3, then add 8. My answer is -1. Choose the correct equation.
3n + 24 = -1
3n - 8 = -1
3(n + 8) = -1
3n + 8 = -1
I think of a number, subtract 7, then multiply by 3. My answer is 4. Choose the correct equation.
n - 7 x 3 = 4
3(n - 7) = 4
3n - 7 = 4
n - 21 = 4
I think of a number, divide it by 3 and then subtract 4. My answer is 5. Choose the correct equation.
3n−4 = 5
n−34=5
3(n−4)= 5
n3 - 4 = 5
Matthew is t years old, Steve is 4 years older than Matthew. Altogether they are 48 years old. Write a simplified equation to show this
t + 4 = 48
t + t + 4 = 48
2t + 4 = 48
t = 22
Kate is x years old, Mohammed is 1 year younger than Kate. Altogether they are 23 years old. Write a simplified equation to show this.
x = 12
2x - 1 = 23
x - x - 1 = 23
x - 1 = 23
Darnesha is w years old. Tia is twice as old as Darnesha. The sum of their ages is 36. Write a simplified equation to show this.
w + 2w = 36
3w = 36
w + w + 2 = 36
w = 12
A rectangular field is y metres wide. Its length is 5 metres longer than its width. The perimeter of the field is 18metres. Write a simplified equation to show this
y + 5 = 18
y + y + 5 = 18
2y + 5 = 18
4y + 10 = 18
Solve 3y−4 = −2
y = -18
y = 6
y = -6
y = -18
Solve 2(y − 3)=−5
y = -7
y = 7
y = 13
y = -13
