5a-2
In order to identify the variable, we need to set the equation equal to zero.
5a-2=0
And then, we solve for the variable.
5a-2=0
5a=2
a=2/5
The variable <em>a</em> is equal to 2/5
Answer:
R(-4,-8) and T(-8,8)
Step-by-step explanation:
- Dilation multiplies or divides. Since it is .5 dilation, the pre-image has greater points.
- This multiplying each end point by 2 gives us our pre-image values.
What you want to do here is plug 2 in for x. when a question asks you to evaluate a certain equation at a certain number, it's just asking you to plug the value in for your variable. i'm assuming that 12x + 8 is meant to be set over 4 as a fraction.
(12(2) + 8)/4 ... figure out the top first. 12*2 = 24, 24 + 8 = 32.
32/4 = 8, so your correct choice is D.
Answer:
1 mile = 160934 cm
Step-by-step explanation:
1 mile = 1609.34 m
1 m = 100 cm
1 mile = 1609.34 * 100 = 160934 cm
20.21 multiplied by 999.801 is 20,205.97821, so the correct answer would be A. about 20,000
