6 Cakes man 6 cakes 42*2 3*2
Answer:
42 slices from 3 cakes = 84 slices from 6 cakesStep-by-step explanation:
Let the unknown value be x
[tex]42 = 3\\84 =x\\\\[/tex]
Cross Multiply
[tex]42\times x = 84\times 3\\\\42x = 252[/tex]
Divide both sides of the equation by 42
[tex]\frac{42x}{42} = \frac{252}{42} \\\\Simplify\\\\x =6[/tex]
Find the missing sides
and the perimeter

1; 5.5x+1-(1.5x+17)
2; x-3x-(-5x)
9514 1404 393
Answer:
4x -16 3xStep-by-step explanation:
Use the distributive property to distribute the outside minus sign to all terms inside parentheses.
1) 5.5x +1 -(1.5x +17) = 5.5x +1 -1.5x -17 = x(5.5 -1.5) +(1 -17)
= 4x -16
__
2) x -3x -(-5x) = x -3x +5x = x(1 -3 +5)
= 3x

The half-life of a radioactive kind of iodine is 60 days. How much will be left after 240 days, if you start with 480 grams of it?
Answer:
30 grams
Step-by-step explanation:
half life is 60 days so every 60 days the amount 480 grams will be half
in 240 days will decay 240 /60 = 4 times
once 480 /2 = 240
twice 240 /2 = 120
trice 120 / 2 = 60
four times 60/2 = 30 grams will be left

???????????????i didn’t learn this what’s the answer ?
Answer:
24 inches squared
Step-by-step explanation:
That is a triangle, and the area of a triangle is 1/2(b)(h), which is one half times the base times the height. Let's identify those things.
1/2: the area of a rectangle can be calculated base times the height, and a triangle is half of that rectangle, hence the 1/2
(b) or base: base is usually identified as the horizontal line in the triangle, which is 6 inches in this case.
(h) or height: height is usually the vertical line, and in this case, the vertical line is 8 inches.
Now time for the math:
1/2(6)(8) = 24 inches squared

Evaluate each expression if m=2, n=16, and p = (Examples 1-6)
1. m + 10

Answer:
1. 12 2. 12 3.1/8 4. 11 5. -15 6.-60 7.20 8.225
Step-by-step explanation:
Given that :
m=2 and n=16 , p = {1-6 =-5} then;
1. m+10 = 2+10 = 12
2. n-4 = 16-4 = 12
3. m / n = 2/16 = 1/8
4. 6m - 1 = 6*2 - 1 = 12 -1 = 11
5. 3p =3* -5 = -15
6.12 p = 12* -5 = -60
7. 12m-4 = 12*2 - 4 = 24 -4 =20
8. 9p² = 9*-5² = 9 * 25 = 225
QUICK PLZ!!! Use the number line below, where RS = 6y + 3, ST = 4y + 7, and RT = 60.
Step-by-step explanation:
[Diagram in image attached]
RS + ST = RT
(6y +3) + (4y + 7) = 60
6y + 3 + 4y + 7 = 60
10y + 10 = 60
10y = 60 - 10
10y = 50
y = 50/10
y = 5
RS = 6y +3 = 6(5) + 3 = 30 + 3 = 33
ST = 4y +7 = 4(5) + 7 = 20 + 7 = 27
RT = 60
{RS + ST = RT
33 + 27 = 60}

The cost for 5 adults and 3 children to attend a show is $210. ( /5)
For 2 adults and 5 children the cost is $160.
Form a pair of simultaneous linear equations and solve them to find the cost of:
i. an adult ticket
ii. a child ticket
Answer: i. Cost of adult ticket = $ 30
ii. Cost of child ticket = $20
Step-by-step explanation:
Define variables:
Let x= cost of 1 adult tickets , y= cost of 1 child tickets.
Form linear equations:
5x+3y = 210 (i)
2x+5y= 160 (ii)
Multiply (i) by 2 and (ii) by 5
10x +6y = 420 (iii)
10x+25y = 800 (iv)
Eliminate (iii) from (iv)
19y = 380
⇒ y= 20
Put this in (i)
[tex]5x+3(20)=210\Rightarrow\ 5x+60 = 210\\\\\Rightarrow\ 5x=150\\\\\Rightarrow\ x=30[/tex]
Hence, Cost of adult ticket = $ 30 and Cost of child ticket = $20

help me please. real answers only. Write an equation for the line parallel to the given line that contains C.
C(2,8); y = - 4x + 5
y =
(Type your answer in slope-intercept form.)
Answer:
y = -4x + 16
Step-by-step explanation:
The slope of the given line is -4
when two lines are parallel, their slopes are equal
That means the slope of the second line is -4 too
Thus, we have to use the point-slope form to write the equation
That will be
y-y1 = m(x-x1)
y-8 = -4(x-2)
y -8 = -4x + 8
y = -4x + 8+8
y = -4x + 16

Answer:
I love ur pfp
Step-by-step explanation:
ANSWER: m∠2 = 120°, m∠3 = 60°; Sample answer: ∠1 and ∠2 are alternate exterior angles, so they have the same measure. ∠2 and ∠3 are supplementary. So, m∠3 = 180° – 120° or 60°.

composition of functions
g(x)=2x-5 h(x)=x^2-2
find g(h(-8))
Answer:
g(h(- 8)) = 119
Step-by-step explanation:
Evaluate h(- 8), then substitute the result obtained into g(x), that is
h(- 8) = (- 8)² - 2 = 64 - 2 = 62, then
g(62) = 2(62) - 5 = 124 - 5 = 119
