Answer:

a) 15/8 b) 25/18

Step-by-step explanation:

a) First bring all the fractions to a common denominator (I'm going to use 8th's). 5/8 is already simplified, 1/2=4/8, and 3/4=6/8. Then, simply add the numerators and leave the denominator: $\frac{5+4+6}{8} =\frac{15}{8}$

Since this can not be simplified any further, your final answer is 15/8.

b) Start by bringing all the fractions to a common denominator (for this problem, we'll use 18th's). 2/3=12/18, 1/6=3/18, and 5/9=10/18. Then just add all the numerators and leave the denominator the same: $\frac{12+3+10}{18} = \frac{25}{18}$

Since this cannot be simplified further either, your final answer is 25/18.

Hope this helps! :)

Solve the following equation, answer as a reduced, mixed number. Then place the correct number in the box provided.

qaws [65]

7(x-2) + 3(x + 2) = 5(x-6)...distribute thru the parenthesis
7x - 14 + 3x + 6 = 5x - 30...combine like terms
10x - 8 = 5x - 30...subtract 5x from both sides
10x - 5x - 8 = -30....add 8 to both sides
10x - 5x = -30 + 8...combine like terms
5x = - 22
x = -22/5 = - 4 2/5 <==

A plot of land has an area of 1,089,000 square feet.The conversion factors between different area measures are shown below.27,87

IgorC [24]

Part A) 24.79 acres

1) Since that plot has an area of

$1,089,000ft^2=1.08\times10^6ft^2$

And the number of units must be between 10 and 10² units.

Part A)

$\begin{gathered} 27,878,400ft^2=2.78784\times10^7ft^2=1m^2 \\ 43560ft^2\text{ =4.356 }\times10^4ft^2\text{ = 1 acre} \end{gathered}$

2) Let's convert them to the apparently plausible units, see if it fits within the given interval.

$\begin{gathered} \frac{1.08\times10^6}{4.356\times10^4}=24.79\text{ acres} \\ \frac{1.08\times10^6}{2.78784\times10^7}=0.03m^{2} \end{gathered}$

We can see that 0.03 m² does not belong to the given interval.

3) Hence, the answer is 24.79 acres.

Rebecca draws two triangles on this coordinate plane.

anzhelika [568]

Answer:

The answer is below

Step-by-step explanation:

From the image attached, the coordinates of triangle ABC are at A(-5, 4), B(-5,7) and C(-2, 7)

a) If a point O(x,y) is rotated 90° clockwise, the new coordinate is O'(y, -x)

If triangle ABC is rotated 90° clockwise, its new coordinate is at:

A'(4, 5), B'(7, 5) and C'(7, 2)

The coordinate of A"B"C" is A"(2,5), B"(5,5), C(5,2)

Hence the transformation used to map A'(4, 5), B'(7, 5) and C'(7, 2) to A"(2,5), B"(5,5), C(5,2) is (x - 2, y + 0). Hence comparing with (x + h, y + k) gives:

h = -2, k = 0

b) If a point O(x,y) is reflected across the y = -x line, the new coordinate is O'(-y, -x)

If triangle ABC is reflected across y = -x, its new coordinate is at:

A'(-4, 5), B'(-7, 5) and C'(-7, 2)

The coordinate of A"B"C" is A"(2,5), B"(5,5), C(5,2)

6*10 =$60 for sugar sticks
14*8=$112 for jelly beans

Thus, $60 + $112 = $172 for overall candy mixture.
