Answer:
multiplication
Step-by-step explanation:
The evaluation of ...
13 -2·3 +4/4 +4
starts with the multiplication, because there are no exponents or parentheses.
13 -6 +4/4 +4
Next is the division:
13 -6 +1 +4
Finally, the addition and subtraction:
7 +1 +4
8 +4
12
_____
We have assumed your x is not a variable, but is intended to indicate multiplication. We have also assumed that your "divided by" implies no particular grouping, so that the numerator is the first preceding number and only the first following number is in the denominator.
Answer:
Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.
Step-by-step explanation:
Let
Inches = x
Feet = y
Constant of proportionality = k
ratio of feet to inches
x = ky
1 feet = 12 inches
12 = k * 1
k = 12/1
k = 12
Ratio of inches to feet.
y = kx
1 = k * 12
k = 1/12
Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.
Answer: ∠ECB = 60°
Step-by-step explanation:
First, find the value of <em>x </em>by adding them up.
x + 3x + 2x = 6x
Since we know that all of the angles create a 180° angle, we can set up a proportion.
6x = 180°
To find the value of x, divide both sides by 6.
6x ÷ 6 = x
180 ÷ 6 = 30
So now the proportion is x = 30.
Now that we now x = 30, we can plug in 30 to the angle measures.
∠DCA = 30°
∠DCE = 90°
∠ECB = 60°
So angle ECB is 60°.
hope this helps!

Answer:
$4500
Step-by-step explanation:
Given data
State income tax= $234
we are told that the tax paid is 5.2% of her income
Let her earnings be x
so
5.2% of x = $234
5.2/100*x=234
0.052x= 234
x= 234/0.052
x= $4500
Hence her earnings is $4500
