If you need help with things like this, put the fractions into decimals.
A number that is less than -2.8 and greater than -3.2
A -3.5
B -3.666
C -2.5
D -2.875
The answer is C
Answer:
x=-0.21...
Step-by-step explanation:
Make the expression equal 0
32x+1-3x+5=0
Combine the x terms
29x+1+5=0
Combine the constants
29x+6=0
Isolate the x term
29x=-6
Isolate the variable
x=-0.21...
(I rounded to the nearest 100th)
Answer:
Cost to a rent a snorkel , Cost on 10 rent snorkel
Step-by-step explanation:
Given,
Tourist spend on rent snorkel and fin=
10 snorkel and 12 pairs of fin
Let the cost to rent a snorkel be =x
and cost of a pair of fin is =y
x=3y (given condition)
Cost of a pair of fin=
Cost of rent a snorkel
Total cost of a rent snorkel
=
On this picture is shown a quadrilateral inscribed in a circle and by the Inscribed Quadrilateral Theorem the angles on the opposite vertices are supplementary, or in other words are equals to 180 degrees.
On this exercise it is asked to find the measure of angle B, First of all, you need to find the value of x. To so you have to select two opposite angles on this case angles A and C.
m<A+m<C=180 Substitute the given values for angles A and C
x+2+x-2=180 Combine like terms
2x=180 Divide by 2 in both sides to isolate x
x=90
Now, that the value of x is known you can substitute it in the expression representing angle D, and then subtract that number from 180 to find the measure of angle B.
m<D=x-10 Substitute the value of x
m<D=90-10 Combine like terms
m<D=80
m<B=180-m<D Substitute the value of angle D
m<B=180-80 Combine like terms
m<B=100
The measure of angle B is 100 degrees, and the value of x is 90.
