Mathematics

38^2x = 109
Apply lg on both sides
lg 38^2x = lg 109
Bring the power down
2x lg 38 = lg 109
2x = lg 109/lg 38
x = (lg 109/lg 38) ÷ 2
= 0.645

Hope it helped!

A package of 5 crackers contains 205 Calories. How many Calories are in one cracker using a double number line
natulia [17]

Answer:

Step-by-step explanation:

since there are 205 calories in 5 crackers we can represent this as

205/5

we need to find how many calories are in one cracker, so lets take "x" as the # of calories in 1 cracker

so

\frac{x}{1} =\frac{205}{5}

cross multiply

5x=205

divide by 5 on both sides

x=41

41 calories in 1 cracker

Number line:

Simplify the following expression by combining like terms.
Aleks04 [339]

Answer:

8x^2+3x

Step-by-step explanation:

What I read is 2x+8x^2-4x+5x

combining like terms means putting the terms that have the same variable part together

8x^2 is the only one that doesn't have any terms like it as far as the variable part

so 8x^2+2x-4x+5x

We just need to figure out 2-4+5 which is -2+5=3

So the answer is 8x^2+3x
