You will need to know how much each lunch cost
so
9.40 <span>÷ 4 = 2.35
so each lunch cost 2.35 dollars
now we need to find out how much it will cost for 10 lunches
10 x 2.35 = 23.5
so for 10 lunches it will cost 23.5</span>
Answer: 8(8u-5)
Step-by-step explanation:
Find a number that goes into both 64 and 40 the GCF of both is 8 so 8 goes on the outside of the new factor 8u-5 because if we distribute back we should arrive at the original equation
8(8u-5)
Answer:39
Step-by-step explanation:
Answer: 13
Step-by-step explanation:
5+2x
When x=4
5+2(4)
5+8
= 13
Answer:
Infinitely many triangles.
Step-by-step explanation:
Given the lengths of two sides are 8 inches and 10 inches.
Let's assume third side = x inches.
Using the Triangle Inequalities given as follows:-
1. a+b > c,
2. b+c > a,
3. c+a > b.
Using the lengths given in the problem, we can write:-
1. x+8 > 10 ⇔ x > 10-8 ⇔ x > 2.
2. x+10 > 8 ⇔ x > 8-10 ⇔ x > -2.
3. 8+10 > x ⇔ x < 18.
So, the solution set is 2 < x < 18. It means third side can take any value in interval (2, 18).
Hence, there are infinitely many triangles.
