Answer: adults = $10
Step-by-step explanation:
x = adults
y = children
2x + 2y = 30
2x + 3y = 35
Using the elimination method:
2x + 2y = 30
-2x - 3y = -35 (multiplied by -1, to give 2x -2x = 0)
Solve for y...
2y = 30
-3y = -35
Add together...
-y = -5
Multiply by -1 to give positive value for y...
y = $5
Plug into one of the original equation to find x...
2x + 10 = 30
2x = 20
x = $10

(20a-10) - (12a-3) subtract
Answer:
8a - 7
Step-by-step explanation:
First, subtract 12a from 20a
20a - 12a
= 8a
Now, subtract -3 from -10.
Subtracting a negative number is the same as adding a positive number, so add 3 to -10.
-10 + 3
= -7
Put together 8a and -7
8a - 7
So, the simplified expression is 8a - 7

Given the points (4,-1) and (3,5), find the slope
A.) 6
B.) -6
C.) 1/6
D.) -1/6
Answer: slope is -6
equation is y=-6x+23
Step-by-step explanation:
mrk brainliest plz
Answer:
B
Step-by-step explanation:
you can use the slope formula which is (y₂ - y₁)/(x₂ - x₁).
Plug the numbers in:
(5 - (-1)/(3-4)
6/-1
= -6
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
Betty babysat for 3 hours each night for 12 nights. She earned a total of $288 babysitting. Betty wants to calculate her hourly rate. How much did Betty earn per hour babysitting?

4. What is the area of the figure at the right?
Answer: 336
Step-by-step explanation:
formula for area of a triangle = bh / 2
12 * 10 = 120 / 2 = 60
12 * 18 = 216 / 2 = 108
60 + 60 + 108 + 108 = 336

Second pic
[tex] < c + 2x + (3x + 10) = 180 \\ < c = 180 - 3x - 10 - 2x \\ < c = 170 - 5x[/tex]
Answer:
Step-by-step explanation:
#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
Answer:
Hello! answer: x = 132
Step-by-step explanation:
This is a supplementary angle meaning it will add up to 180 degrees 180 - 48 = 132 therefore x = 132 HOPE THAT HELPS!

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.

Answer:
D) p³ + 2; when p = 3 the number of plants is 29.
Step-by-step explanation:
Illiana cubed (³) the number of original plants, p, in the garden. Then, she added 2 more plants. We will use n for the number of total plants.
So, the equation should be p³ + 2. Substitute our value for p into the equation and solve.
p³ + 2 = n
3³ + 2 = n
27 + 2 = n
29 = n
There are 29 total plants.
The answer, then, is the last option, p³ + 2; when p = 3 the number of plants is 29.
Good luck ^^

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
