13(y - 10) = -4

13y - 130 = -4

13y - 130 + 130 = -4 + 130

13y = 126

13y/13 = 126/13

y = 126/13

How do I solve question 13 and 14?

xxMikexx [17]

Answer:

13. 13 or 17 (not sure about this, sorry)

14. 28

Step-by-step explanation:

13.

$a_{n} = \{a_{0}, a_{1}, a_{2}, a_{3}, a_{4}, ... \} \\$

if counting the sequence from $a_{0}$ then $a_{4}$ is 17, but if

$a_{n} = \{a_{1}, a_{2}, a_{3}, a_{4}, a_{5}, ... \} \\$

counting from $a_{1}$ , then $a_{4}$ is 13.

14.

$a_{10} = 1 + 3(10 - 1) = 1 + 3*9 = 28$

NEED HELP ASAP PLEASE

Ilya [14]

Answer:

see explanation

Step-by-step explanation:

Given

A = $\frac{1}{2}$ bh

a. substitute b = 6 and h = 5 into the formula

A = $\frac{1}{2}$ × 6 × 5 = $\frac{1}{2}$ × 30 = 15 units²

Multiply both sides of the formula by 2

2A = bh, that is

bh = 2A ← divide both sides by b

h = $\frac{2A}{b}$ = $\frac{2(16)}{4}$ = $\frac{32}{4}$ = 8

Using

bh = 2A ← divide both sides by h

b = $\frac{2A}{h}$ = $\frac{2(12)}{4}$ = $\frac{24}{4}$ = 6

What is the probability of rolling a 4 on a number cube and then flipping a head on a coin?

spin [16.1K]

Answer:

I think it's 1/6 for the cube and 1/2 for the coin. so it would be 2/8 which would be 1/4 simplified, so in decimal form the probability is .25
