Answer:
15/100 * 20, because the meal is 20 dollars and to find the percent of something you divide it with 100 so you will divide 15 with 100 and you’ll get 0.15. Then you will times it with the amount the meal cost because thats the charge. So 0.15•20 and you’ll get $3. A 15% tip for a $20 meal is $3.
The solution is, option d.) 15/100 * 20,

Determine the GCF of 18xy and 12xy
Answer:
If im correct im pretty sure its 6xy
The GCF of 18xy and 12xy is 6xy.
What is Greatest Common Factor?The largest factor that splits both numbers is said to be the greatest common factor. List the prime factors of each integer before calculating the greatest common factor.
18 and 24 share one 2 and one 3 in common.
, so 2 x 3 = 6 is the GCF of 18 and 24.
Given:
18xy and 12xy
now, factoring the above terms
18xy = 2 × 3 × 3 × x × y
12xy= 2 × 2 × 3 × x × y
So, 18xy & 12xy = 2 x 3 xy = 6xy
hence, the GCF of 18xy and 12xy is 6xy.

A line passes through the point (10,2) and has a slope of 1/2. Write an equation in slope-intercept form for this line.
Answer:
Step-by-step explanation:
y - 2 = 1/2(x - 10)
y - 2 = 1/2x - 5
y = 1/2x - 3
Answer:
Step-by-step explanation:
You can read the slope right away.
y = 0.5x + b 1/2 = 0.5
The point will determine the y intercept
2 = 0.5*10 + b
2 = 5 + b
2-5 = b
b = - 3
The line is y = 0.5x - 3

What is the equation of the line that passes through the point (−3,4) and has a slope of 1 ?
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1, thus
y = x + c ← is the partial equation
To find c substitute (- 3, 4) into the partial equation
4 = - 3 + c ⇒ c = 4 + 3 = 7
y = x + 7 ← equation of line

I hope this helps :>Nate has an account that pays 2.76% simple interest per year and wants to accumulate $3,090 in interest from it over the next 15 years. How much money should Nate invest in this account to meet this goal?
a
$4,369.26
b
$4,373.77
c
$1,279.26
d
$7,463.77
Answer:
To achieve this goal, he must invest $7,463.77 ( d)
Step-by-step explanation:
mathematically;
simple interest = PRT/100
I = 3,090
P = ?
R = 2.76%
T = 15 years
3,090 = P * 2.76 * 15/100
100 * 3090 = 41.4 P
P = 309000/41.4
P = 7,463.77
