The difference between two numbers is 5, and 2 times the lesser number is 18 more than the greater number. Find the numbers.
Answer:
Let x and y be the numbers, with x the larger one.
x - y = 5
2y = x + 18
Then solve this system of equations:
x - y = 5
x - 2y = -18
Subtract bottom equation from top equation and get
y = 23
So x = y + 5 = 23 + 5 = 28

Apply the distributive property to create an equivalent expression.
(3−8y)⋅(−2.5)=
Answer:
-7.5+20y
Step-by-step explanation:
To apply the distributive property, you have to distribute the multiplication of -2.5 to both 3 and -8y.
First, multiply 3 and -2.5 to get -7.5
Then, multiply -8y and -2.5 to get 20y.
Finally, add these values together

Answer:
1) x = 13 (because other angle of the triangle is 45°.Then the foots faced to equal angles are equal)
Then we can calculate y by pythagoras law
[tex] {y}^{2} = {x}^{2} + {13}^{2} \\ {y}^{2} = {13}^{2} + {13}^{2} \\ y = \sqrt{2 \times 169} \\ y = 13 \sqrt{2} [/tex]

You jog 623 miles around a track each day. If you jogged that distance 4
times last week, how many miles did you jog? in a fraction
Answer:
6 2/3 miles times 4
Step-by-step explanation:
Convert the fraction 2/3 to a decimal
2/3 = .67
6.67 miles times 4 = 26.68 miles
or 6x4= 24
2/3+2/3+2/3+2/3 =8/3 or 2 2/3
2 2/3 +24 =26 2/3 miles

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The sum of the product of 3/5 and 5/9 and the product of 5/9 and 3/20 is 5/12.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The product of 3/5 and 5/9 is,
Product = 3/5 × 5/9
= (3×5)/(5×9)
= 15 / 45
= 1/3
The product of 5/9 and 3/20 is,
Product = 5/9 × 3/20
= (5×3)/(9×20)
= 15 / 180
= 1/12
Now, the sum of the two products can be done as shown below,
Sum = 1/3 + 1/12
= 4/12 + 1/12
= (4+1)/12
= 5/12
Hence, the sum of the product of 3/5 and 5/9 and the product of 5/9 and 3/20 is 5/12.

Find the slope of the line that passes through each pair of points (-7,-6) (3, -6)
Answer:
0
Step-by-step explanation:
Slope = Change in Y/Change in X
Slope = -6 - (-6)/3 - (-7)
Slope = 0/10
Slope = 0
This is a horizontal line
-Chetan K
Answer:
Let (-7, -6) be (x1, y1)
and (3, -6) be (x2, y2)
The slope can be found with [tex]\frac{y2-y1}{x2-x1}[/tex]
Substitute in values:
[tex]\frac{-6-(-6)}{3-(-7)} =0[/tex]
The slope is 0. (It is a horizontal line.)
ONLY BOTS WITH LINKS KEEP ANSWERING MY QUESTION PLEASE SOMEONE HELP ME WITH THIS
You didn't really describe what we're supposed to do, but I'm going to assume they want you to graph it.
The first equation has a slope of 3/5x, meaning that for every 3 units it moves upwards, it moves right 5 units. It has a y-intercept of 8, meaning that the line will cross through (0, 8) on the coordinate plane. Start your point on (0, 8) and draw a line that goes up 3 units and 5 units.
The second equation has a slope of -4/5x, meaning that for every 4 units it moves upwards, it moves left 5 units OR for every 4 units it moves down it moves 5 units right. The y-intercept is 1, so the line will go through (0, 1). Start your point on (0, 1), and draw a line that follows the slope, just like last time.
If this is all correct and the best answer, please give me brainliest as I'm trying to rank up. Thanks!

In figure BC = CA and ∠A = 40°. Then ∠ACD is...
a)40° b) 80° c) 120° d) 60°
Answer:
B
Step-by-step explanation:
The size of the exterior angle in a triangle is the sum of interior opposite angles. In this case, it's
Angle ACD=40+40=80° (Exterior angle=sum of int. opp. angles)
Answer:
b. 80°
Step-by-step explanation:
B is 40°
A triangle has 180°
40 + 40 + x = 180
80 + x = 180
x = 100
Since it's a supplementary angle...
180 - 100 = 80
What is an equation of the line that passes through the points (6, -3) and
(-6, -5)?
Answer:
Step-by-step explanation:
The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
We can calculate the slope from the two given points, (6,-3) and (-6,-5). Slope is Rise/Run, where Rise is the change in y and Run is the change in x.
From the two given points, starting at (-6,-5) and going to (6,-3):
Rise = (-3 - (-5)) = +2
Run = (6 - (-6)) = 12
Rise/Run (slope) = 2/12 or 1/6
The equation becomes y = (1/6)x + b
We can find b by enterieng either of the two given points and solving for b. I'll pick (6,-3):
y = (1/6)x + b
-3 = (1/6)*(6) + b
-3 = 1 + b [Now you can see why I chose (6,-3)]
b = -4
The equation is y = (1/6)x - 4
