Answer:
Step-by-step explanation:
let the number of children be x
and the number of adults be y
so
7x+12y=236-----1
and
14x+7y=217------2
equating both 1 and 2 we have
7x+12y=236-----1
14x+7y=217------2
multiply 1 by 2
subtract 2 from 1 we have
14x+24y=472-----3
- 14x+7y=217------2
0x+17y=255
17y=255
y=255/17
y=15
put y=15 in eqn 1 we have
7x+12y=236-----1
7x+12*15=236-----1
7x+180=236-----1
7x=236-180
7x=236-180
x=56/7
x=8
therefore a child will cost $8 and adult will cost $15

Cherries are on sale at the grocery store at a price of $5 for 2 pounds. Oscar buys 3
pounds. If he is charged the sale price for the cherries, how much will Oscar pay?
Answer:
$7.5 = 3 pounds
Step-by-step explanation:
1. If $5 is equal to 2 pounds of cherries, you want to find what 1 pound of cherries cost. You should divided 5 by 2 and 2 by 2 to find what 1 pound of cherries cot.
2. That means that 1 pound of cherries cost $2.5.
3. Now we want to find how much money 3 pounds cost, so you should multiply the 2.5 and the 1 by 3.
4. Now that gets you to $7.5 for 3 pounds of cherries.s
1. Find the values of the
angles x, y and z.
40°
25°
z
у
Answer:
z = 40° (V. O. A)
Now find x
40 + 25 + x = 180(A. S. P)
65 + x = 180
x = 180 - 65
x = 115°
Now find y
x = y (V. O. A)
Y = 115°
So angles are
X = 115°
Y = 115°
Z = 40°
Hope this helps, have a great day, have a wonderful weekend and stay safe!

A: x = 10
B: x = 4
C: x = -14
D: x= -17
Answer:
x=4
Step-by-step explanation:
Answer:
B) x=4
Step-by-step explanation:
Identify an equation in point-slope form for the line perpendicular to
y=-1x +11 that passes through (4, -8).
O A. y +8 = 2(x-4)
B. y - 4 = 2(x+8)
O C. y+8 = {(x-
-4)
O D. 7-8 = {(x + 4)
Answer:
C
Step-by-step explanation:
Perpendicular lines have the exact opposite slope of the other equation.
So the slope will be x or 1x. Plug in
-8 = 1(4) + b (b represents y-intercept) like y=mx+b
-8 = 4 + b (subtract 4 on both sides)
-12 = b
The equation is y = x - 12
C
solve
y + 8 = x - 4 (subtract 8 on both sides)
y = x - 12

is this 9th grade math????
Step-by-step explanation:
1
could some one please help I'm not that good with math
Answer:
D and E
Step-by-step explanation:
It is acute because all angles are under 90 degrees. This means that it cannot be F, obtuse. It cannot be A because A scalene triangle is a triangle in which all three sides have different lengths. It cannot be B either because it has 3 sides of equal angles. It cannot be right because non of the angles are 90 degrees. It is equilateral.
Hope this helps.

Tamar used the algebraic method to convert the repeating decimal number to 2.45 to a fraction. Her first two steps are shown below. Step 1: x=2.45. Step 2: 100x=245.45. What should be Tamar’s next step
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
x = 2.4545... → (1)
100x = 245.4545... → (2)
Subtract (1) from (2) eliminating the repeating decimal
99x = 243 ( divide both sides by 99 )
x = [tex]\frac{243}{99}[/tex]

Step-by-step explanation:
For a craft project, four students each chose three pieces of wire from a box. Don's wires measure 3 inches, 5 inches, and 12 inches. Margo's wires measure 6 inches, 8 inches, and 14 inches. Sonji's wires measure 12 inches, 8 inches, and 17 inches. Liam's wires measure 16 inches, 8 inches, and 27 inches.
Answer:
Sonji's wires measure will be chosen
Step-by-step explanation:
Given:
Don's wires measure = 3 inches, 5 inches, and 12 inches
Margo's wires measure = 6 inches, 8 inches, and 14 inches
Sonji's wires measure = 12 inches, 8 inches, and 17 inches
Liam's wires measure = 16 inches, 8 inches, and 27 inches.
Find:
Measure used to construct a triangle
Computation:
In a triangle sum of two smaller side is grater then bigger side
a + b > c
So.
Don's wires measure = 3 inches + 5 inches < 12 inches
Margo's wires measure = 6 inches + 8 inches = 14 inches
Sonji's wires measure = 12 inches + 8 inches > 17 inches
Liam's wires measure = 16 inches + 8 inches < 27 inches.
So,
Sonji's wires measure will be chosen

2,3,5,7,11,13 conjecture
Answer:
The primes up to 50 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47. The sequence of gaps—the differences between each prime and the next—is 1, 2, 2, 4, 2, 4, 2, 4, 6, 2, 6, 4, 2 and 4. The number 1 appears only once because all primes except for 2 are odd. The rest of the gaps are even numbers.
The conjecture which could be inferred from the sequence is that it is a list of prime numbers.
From the sequence given : 2, 3, 5, 7, 11, 13
All values in the sequence are prime numbers.
Prime numbers are numbers which have only two divisors which are 1 and the number itself.
Divisors of :
2 = 1 and 2
3 = 1 and 3
5 = 1 and 5
7 = 1 and 7
11 = 1 and 11
13 = 1 and 13
Hence, the conjecture which could be inferred from the sequence is that, the numbers are prime numbers.
