Answer:
x=10, y=-5
Step-by-step explanation:
2x+3y=5, y= 5-x; change y to 5-x:
2x+3(5-x)=5
2x-3x+15=5
-x=5-15
-x=-10
x=10
=>y=5-x=5-10=-5

Answer:
d = t(.7)
Step-by-step explanation:
We can start by dividing the values on the right by the values on the left.
Starting with the first one, 7/10=.7
It gives us .7
To double check this we can use the second values, 10.5/15=.7
It gives us .7
and even if we still aren't sure we see the last value also gives us the same answer, 14/20=.7
This means that if we multiplied the time by .7 for any of the time values, we would get our distance values.
Hope this helps! :)

On the line that passes through point C, mark a point D that is distinct from point C. Use the slope formula along with coordinates of points to find the slopes of and . Show your work.
Answer:
PLATO
Step-by-step explanation:
Answer:
The coordinates of point D will vary based on the point location, but the resulting slope of the line through points C and D will be the same.
A = (-3, 3), B = (-1,-1)
Slope of AB = (YB−YA) / ( XB –XA) =−1−3 / −1−(−3)= − 4 / 2= −2
D = (-1,6), C = (1,2)
Slope of DC = (YC−YD) / (XC−XD)= 2 – 6 / 1−(−1)=−4 / 2=−2

Yesenia has a 13 ft ladder that she placed against a
wall. How far up the wall will the ladder reach when the
base of the ladder is 5 ft from the wall?
Answer:
12 ft
Step-by-step explanation:
Using formula (pythagorean theorem)
a² + b² = c²
Where :
13 = c
and 5 = a
5² + b² = 13²
25 + b² = 169
169 - 25 = b²
144 = b²
Sq root b = 12
It will reach up 12 ft.

does 4(x+1)=2x+4 have a solution
Answer: Yes, x = 0
Step-by-step explanation:
To solve for x, we will simplify things by distributing the 4 to the (x + 1) term. This means that our new equation will be
4x + 4 = 2x + 4
Now that we have our new equation, we will isolate x by subtracting 4 from both sides. After this, we will end up with
4x = 2x
At first glance, this may seem like no solution. What number has the same value when multiplied by 2 and by 4? Well, there infact is one. This can be shown when we subtract both sides by 2x to keep x on one side, and get
2x = 0
Divide by both sides to isolate x, and you get x = 0/2 = 0.
Thus, x = 0.

#1Circumference equation:
C = πdCircumference to diameter ratio is:
C/d = π = 3.14Same result comes from the tableCorrect choice is B#2Sum of angles of a triangle is 180°
m∠A + m∠B + m∠C = 180°A and C are equal angles as opposite sides are congruent.
2(3x + 10) + 2x = 1806x + 20 + 2x = 1808x = 160x = 20m∠C = 3*20 + 10 = 70°Help ASAP plsplsplsplsplsplspls

Judys town voted on a new speed limit. 95% of the 2,000 votes were in favor of the new speed limit. How many voted were in favor
Answer:
1,900 votes were in favor.
Step-by-step explanation:
Given that the statement indicates that 95% of the 2,000 votes were in favor, you can find the number of votes in favor by calculating the 95% of the total number of votes:
2000*95%=1900
According to this, the answer is that 1,900 votes were in favor.

You are making powdered drink mix. You mix 3 teaspoons of drink mix with 1 cup of water for 1 serving.
How much mix and water do you need for 7 servings?
How much mix and water do you need for 2 servings?
Answer:
For 7 servings, you need 21 teaspoons of drink mix and 7 cups of water
For 2 servings, you need 6 teaspoons of drink mix and 2 cups of water
Step-by-step explanation:
Since you need 3 teaspoons of drink mix per serving, multiply number of servings by 3 to find teaspoons of drink mix
Since you need 1 cup of water per serving, the number of servings is equal to the number of cups

Answer: The error is the number of sides, it should be 9 sides and not 25. Correct is 1 260 degrees
Step-by-step explanation:
The error is the number of sides, it should be 9 sides and not 25.
Polygon sum of interior angles formula: 180 x (n-2)
So here n = 9 (sides)
180 x (9-2)
180 x 7 = 1 260 degrees
Answer:
sum of interior angles = 180 * n - 2
n = number of sides
in this case, the shape has 9 sides so n = 9
so the correct answer should be
= 180 * (9-2)
= 180 * 7
= 1260
