Answer:

x≥−3

Step-by-step explanation:

−4x−10≤2

Step 1: Add 10 to both sides.

−4x−10+10≤2+10

−4x≤12

Step 2: Divide both sides by -4.

−4x−4≤12

The ratio of red to blue marbles in a bag is 2:5. If there are 65 blue marbles in the bag, how many red marbles are there? Let x

hoa [83]

Answer:

first get the total ratio; 2 + 5 = 7

so the fraction of blue marbles is 5/7

then assume the number of total marbles to be k

then use the expression;

5/7*k = 65

7*5/7 * k = 65*7

5k =455

5/5k = 455/5

k = 91

then calculate the number if red marbles from;

x = 2/7*91

x = 26

Therefore there are 26 red marbles.

The drama club is planning a field

Inessa [10]

Answer:

$\frac{2}{3}s+8=48$ .

Step-by-step explanation:

If we indicate the amount of students in the drama club as"s", we know that $\frac{2}{3}s$ is attending to the trip.
We also know that there are will be 8 teachers in the trip as well.
If the total amount of persons that will go on the trip reachs 48, which is the sum of 8 teachers and the $\frac{2}{3}s$ of the students: $\frac{2}{3}s+8=48$ .

Then, the equation that describes the situation is $\frac{2}{3}s+8=48$ . If we subtract 8 from both sides of the equation, and then we have $\frac{2}{3}s=40$ , which means that s=60.

Tomas has a garden with a length of 2.45 meters and a width of 5/8 meters. Use benchmarks to estimate the area and perimeter of

Alchen [17]

Answer: The area is 1 1/4. The perimeter is 6.

Step-by-step explanation: 2.45 is about 2.5. 5/8 is about 1/2. To find the area we need to multiply length times width. 2.5 is 2 and 1/2 which is 5/2. 5/2 times 1/2 is 5/4. To simplify it divide 5 by 4 which is 1 with remainder 1. 5/4 is 1 1/4. Therefore the area is 1 1/4 meters squared. To find the perimeter we have to add length + length + width + width. . 2.5 is the same thing as 2 1/2. 5/8 is about 1/2 if we use benchmarks. 2 1/2 + 2 1/2 + + 1/2 + 1/2 is 6. The perimeter is 6.
