Tju [1.3M]

Answer: 35

Step-by-step explanation:

Given : At Deb’s Deli, a customer may choose either a sandwich and a salad or a sandwich and a soup for the lunch special.

The number of choices for sandwiches = 5

The number of choices for salad = 4

The number of choices for soup = 3

Now, the number of possible lunch special combinations can be ordered will be :-

$5\times4+5\times3=20+15=35$

Hence, the number of possible lunch special combinations can be ordered will be 35.

5i) a+b

3.1+7.3

=10.4

ii) b-a

7.3-3.1

=4.2

5 and 6 are both similar. Just place the numbers instead of the letters

6i) x+y

Solve 5c − c + 10 = 34.

makkiz [27]

Answer: 6

Step-by-step explanation: 1. 5c-c= 4c. The equation would then be 4c+10=34.

2. From there, you subtract 10 from both sides of the equation. By doing this, you have the variable and the nonvariable on separate sides of the equation.

3. After doing that, you should have 4c=24. To get the variable by itself, divide both sides by 4. 4c/4 is c and 24/4 is 6.

The final answer is 6. Hope this helped you:)

Answer:

D. Henry's started farther, went faster

Step-by-step explanation:

Henry's balloon traveled 18 additional miles (from 30 to 48) in 2 hours, so had a speed of 18mi/(2h) = 9 mi/h. The equation for his position could be ...

y = 9x +30 . . . . . 9 is the rate of change; 30 is the initial value

__

Comparing this to Tasha's position function, we see her balloon started 20 miles from town and traveled 8 miles per hour.

__

Henry started farther from town and traveled faster.
