2 answers:
dolphi86 [110]3 years ago
7 0

Answer:

2. x > 17

3. x ≤ 7

4. a < 4

5. t ≥ -2

Step-by-step explanation:

2). x - 7 > 10

Now we add 7 on both the side of the inequality [Both the side of sign (>) greater than].

x - 7 + 7 > 10 + 7

x > 17

Answer is x > 17

3). 3x ≤ 21

Now we divide by 3 on both the sides of the inequality.

\frac{3x}{3} ≤ \frac{21}{3}

x ≤ 7

Answer is x ≤ 7

4) 5a - 2 < 18

(5a -2) + 2 < 18 + 2

5a < 20

\frac{5a}{5}

a < 4

Answer is a < 4

5). 2t + 8 ≥ -4(t + 1)

2t + 8 ≥ -4t - 4

2t + 8 - 8 ≥ -4t - 4 - 8

2t ≥ -4t - 12

2t + 4t ≥ -4t + 4t - 12

6t ≥ -12

t ≥ -\frac{12}{6}

t ≥ -2

Answer is t ≥ -2

Kelly divided of 5/7 a liter of plant fertilizer evenly among some smaller bottles. She put 1/5 of a liter into each bottle. How
worty [1.4K]

Answer:

3 bottles

Step-by-step explanation:

Given that :

Total liters of fertilizer = 5/7 litres

Amount put into each smaller bottle = 1/5 liters

Number of small bottles filled :

Total liters of fertilizer ÷ amount put into smaller bottles

5/7 litres ÷ 1/5 litres

5 /7 * 5 /1

= 25 / 7

= 3.57

Hence, 3 bootles was filled

The equation (x − 5)2 + (y + 3)2 = r2 represents circle T. The point S(-1,6) lies on the circle. What is r, the length of the ra
adell [148]

Answer:

r = 2.4  

Step-by-step explanation:

First of all, note that point S(-1,6) corresponds to S(x,y), therefore:

x = -1

y = 6

Now putting the value of x and y into the equation: (x − 5)2 + (y + 3)2 = r²

(x − 5)2 + (y + 3)2 = r²

(-1 − 5)2 + (6 + 3)2 = r²

(-6)2 + (9)2 = r²

-12 + 18 = r²

6 = r²

r = √6 = 2.4

∴ r = 2.4
