1. 
(a) amount of potting soil he purchased last week
(b) 28 = 2p + 4
(c) 28 = 2p + 4
     28 - 4 = 2p
      24 = 2p
     24/2 = p
     12 = p 
(d) last week, he bought 12 lbs of potting soil

2. F = ma
(a) F/m = a
(b) -25/10 = a
      -2.5 = a
(c) F = ma
     25 = 5m
      25/5 = m
      5 = m

3. 
(a) cost of the t-shirt
(b) 12 + x = 23
(c) 12 + x = 23
      x = 23 - 12
      x = 11
(d) the t-shirt (x) cost $ 11

You go to the store and pick out 3 apples for $0.60 each, 2 bananas for $0.50 each, and 1 quart of yogurt for $4.50. At checkout
Thepotemich [5.8K]

Answer:

I'm not 100% sure but I think it's $6.20

Step-by-step explanation:

First you add up the apples which equals $1.80 then you add up the bananas which equals $1.00 then you add the yogurt together which amounts to $4.50. After that you add all of that together which totals to $7.30.

For the sake of finding the percentage we're gonna move the decimal point to the very end. ( so its 730.0). Now in order to find 15% we have to find 10%. To find 10%, you move the decimal point over one (73.00). So 10% of 730 is 73. 10% + 5% = 15%. And half of 10% is 5%. So, we cut 73 in half so now we have 36.5. Now we add 36.5 to 73 (because 10% + 5%=15%) I'm just gonna round 36.5 to 37, and 73+37= 110. Now we move the decimal point back so its $1.10. Now we subtract $1.10 from $7.30 which is equal to $6.20. So your answer is $6.20.

(I'm rlly bad at explaining things so sorry if this wasnt clear enough. Also I'm not the best at math but I guess I know percentages.)

What is the slope of the line passing through the points (–1, 3) and (4, –7)?
Nataliya [291]
Slope=rise/run
slope=(y2-y1)/(x2-x1) if you have the points
(x1,y1) and (x2,y2)

we have the points (-1,3) and (4,-7) 
x1=-1
y1=3
x2=4
y2=-7

slope=(-7-3)/(4-(-1))=-10/5=-2

The side RS is 7 cm. For a similar triangle, the ratio of the opposite side of the two similar triangle are the same.

<h3>What is SAS similarity theorem?</h3>

ΔABC ~  ΔDEF only if the ratio of two sides of ΔABC and corresponding two sides of ΔDEF is equal, and the angle included in both sides are congruent.

Suppose the two sides of ΔABC are AB and BC, and that of DEF be DE and EF, then for SAS similarity, we need

For the similar triangle;

\rm \frac{HG}{TS} = \frac{FG}{RS} \\\\ \frac{12}{4} =\frac{21}{RS} \\\\ RS= 7 cm

Hence, the side RS is 7 cm.]
