Find the slope of the line that passes through (1, 13) and (10, 6).
Answer:
-7/9
Step-by-step explanation:

the baker family goes out for supper and the price of the meal is $58. the sales tax on the meal is 6.5% and the family leaves a 20% tip on the pre- tax amount. what is the total cost of the meal?
Answer:
$73.37 is the new price.
Step-by-step explanation:
0.065 x 58 = 3.77
0.2 x 58 = 11.6
3.77 + 11.6 = 15.37
15.37 + 58 = 73.37
25 points and brainliest for correct answer pls
A = lw
A = 9
9 = lw
9 = (x + 2)(x + 3)
9 = x² + 3x + 2x + 6
9 = x² + 5x + 6
x² + 5x = 3
Answer:
A = lw
A = 9
9 = lw
9 = (x + 2)(x + 3)
9 = x² + 3x + 2x + 6
9 = x² + 5x + 6
x² + 5x = 3

5% of ______ is 10
_____ % of 100 is 12
Step-by-step explanation:
let the number represent X
5/100xx=10
5x/100=10
then you cross multiply
5x=100x10
5x=1000
divide both sides by 5
X=1000/5 =200

4. Michelle walked 98,094 steps this week. Her best friend Nadia, walked 15,947 steps more than Michelle. How many steps did Nadia walk this week? Show how you solved this problem.
Answer: 114,041 steps
Step-by-step explanation:
No. of steps by Michelle = 98,094
No. of steps by Nadia = 15,947 + Michelle's steps
= 15,947 + 98,094
Nadia's steps = 114,041

How do you solve the equation 4a+b=12
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*a+b-(12)=0
Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 4a+b-12 = 0 and calculate its properties
Notice that when a = 0 the value of b is 12/1 so this line "cuts" the b axis at b=12.00000
b-intercept = 12/1 = 12.00000
When b = 0 the value of a is 3/1 Our line therefore "cuts" the a axis at a= 3.00000
a-intercept = 12/4 = 3
Slope is defined as the change in b divided by the change in a. We note that for a=0, the value of b is 12.000 and for a=2.000, the value of b is 4.000. So, for a change of 2.000 in a (The change in a is sometimes referred to as "RUN") we get a change of 4.000 - 12.000 = -8.000 in b. (The change in b is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -8.000/2.000 = -4.000
Geometric figure: Straight Line
Slope = -8.000/2.000 = -4.000 a-intercept = 12/4 = 3 b-intercept = 12/1 = 12.00000Answer:
Step-by-step explanation:
Without having a numerical value for a (or b), you can't "solve this equation."
You can, however, solve it for either a or b, but not both.
For a: Subtract b from both sides. This results in 4a = 12 - b. Dividing both sides by 4 isolates a:
12 - b
a = --------------
4
For b: Subtract 4a from both sides. Then: b = 12 - 4a
Sean bought 1.8 pounds of gummy bears and 0.6 pounds of jelly beans and paid $10.26. He went back to the store the following week and bought 1.2 pounds of gummy bears and 1.5 pounds of jelly beans and paid $15.09. What is the price per pound of each type of candy?
Answer:
Gummy bears $3.20/lbs
Jelly beans $7.50/lbs
Step-by-step explanation:
For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):
1.8x + 0.6y = 10.26
1.2x + 1.5y = 15.09
Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)
Use the graph to answer the following…
Answer:
slope = 2 because it goes up by 2 and across 1
10 = 2(1)+b
10=2+b
-2 -2
b = 8
y intercept = 8
equation: y = 2x+8
yes it is proportional because it has a constant rate of change or slope

If car number plates have 3 English alphabet letters followed by 3 digits, how many of these start with ABC?
Answer:
351520000
Step-by-step explanation:
351520000
Explanation:
There are 10 possible digits for the numbers (0,1,2,...,9), and 26 possible letters (A,B,C,.....,Z).
Since repetitions are allowed, we have that for each letter used, 26 still remain for the next choice, and for each digit used, 10 still remain for the next choice.
Hence, by the multiplication principle, the total different number of letter permutations is
26
×
26
×
26
=
17576
and the total number of digit permutations is
10
×
10

10
=

But now since they can be in any order, we basically require in how many different ways can 3 be chosen from 6 which is the combination
6

So for each of the original permutations of numbers and letters, we must consider the 20 different combinations of positions they can be in.
Therefore by the multiplication principle, the total possible different number plates is

How do I solve this?
Answer:
100 miles.
Step-by-step explanation:
The combined speed of the 2 trains = 38 + 42 = 80 mph.
The time taken before they crossed = 15:35 - 14:20
= 1:15 = 1.25 hours
Speed = distance / time, so
80 = distance / 1.25
Distance = 80 * 1.25
100 miles.
Answer:
100 miles
Step-by-step explanation:
A -----------P------------------ B
tom start at 14:20 with speed of 38mph
ben with speed 42mph
meeting time is 15:35
time difference is 75 min = 75/60 = 1.25 hours
distance travelled by tom is AP
AP = v * t
= 38 * 1.25
= 47.5 miles
distance travelled by ben is BP
BP = v * t
= 42 * 1.25
= 52.5 miles
distance between two cities is AB = AP + PB
= 47.5 + 52.5
= 100 miles
