Answer:

22 cards

Step-by-step explanation:

Set up a ratio.

\frac{34}{29+x} =\frac{2}{3}

58+2x=102

2x=44

x=22

Check: Add 22 to 39. 22+29=51

34/51 = 2/3

Have a great day

Letter b on number 11 is all I need help with. Thank you
Simora [160]

distance = 500 feet

Since Δ VWX and Δ YZX are similar then the ratios of corresponding sides are equal, that is

\frac{VW}{YZ} = \frac{VX}{YX} = \frac{WX}{ZX}

completing the required values gives

\frac{100}{l} = \frac{60}{30} ( cross- multiply )

60l = 30 × 100 = 3000 ( divide both sides by 60 )

l = 500

distance across the swamp is 500 feet

Combine the like terms to create an equivalent expression: \large{-k-(-8k)}−k−(−8k)minus, k, minus, (, minus, 8, k, )
PIT_PIT [208]

Answer:

7k

Step-by-step explanation:

The given expression is

-k-(-8k)

We need to find the simplified form of the given expression.

Like terms: The terms which have same variables of same degree and known as like terms. For example: 2x and 4x are like terms.

The given expression can be rewritten as

-k+8k

On combining like terms we get

(-1+8)k

7k

Therefore, the equivalent expression of the given expression is 7k.
