Hi there!
To solve your answer, since we know a = 7, we can easily solve your equation.
But before we go onto that, I want to show you a tip or two about solving equations with variables next to numbers.
When you have a number, and a variable attached to it, it means to multiply.
Now, to make this equation look a little easier, lets rewrite it.
9 × 7 - 5 × 7 = ___
According to PEMDAS, we won't go straight from left-to-right when solving here. We'll skip around a little.
9 × 7 = 63.
5 × 7 = 35.
Now, since we've multiplied the two numbers, its time to subtract them.
63 - 35 = 28. Sooooo........
9 × 7 - 5 × 7 = 28
Hope this helps!
Message me if you need anything else, I'd be happy to help you out! :D
A. 1206 cm
B. 2170 cm
C. 3260 cm
D. 6510 cm
Answer:
A
Step-by-step explanation:
V=(pi)(r^2)(h/3)
This is the formula for volume
V=3.14(12^2)(8/3)
plug this into a calculator and make sure you use parenthesis!
V=1205.76
The answer is A
-5x-3y=16
y=x
Answer:
x = 6 possibly
Step-by-step explanation:
I am just an algebra student, but if I am correct I would appreciate a crown.
16/4 is 4, so i assumed that was the geometric pattern, so i divided 24 by 4 and got 6.
Hoped this helped.
Thank you so much!
I literally have no idea how to do this.
