Answer: x= 1.75
Step-by-step explanation:
3.5(2.25+x)= 14 *distribute 3.5 into parentheses*
(7.875+ 3.5x)=14 *subtract 7.875 from both sides*
3.5x= 6.125 *divide*
Your answer is 1.75.
The cost to mail a package is $5.00. Noah has postcard stamps that are worth $0.34 each and first-class stamps that are worth $0.49 each. a. Write an equation that relates the number of postcard stamps p, the number of first-class stamps f, and the cost of mailing the package.
Answer:
[tex]0.34p + 0.49f = 5.00[/tex]
Step-by-step explanation:
Given
[tex]Cost = \$5.00[/tex]
[tex]Postcards = \$0.34[/tex]
[tex]First-class = \$0.49[/tex]
Required
Represent as an equation
If 1 postcard costs $0.34, then p postcards cost $0.34p
If 1 first-class costs $0.49, then f first-class cost $0.49f
The addition of p postcards and f first-class equals the total cost of mailing the package.
So, we have:
[tex]0.34p + 0.49f = 5.00[/tex]

Answer:
[tex]\frac{15}{10}[/tex] and [tex]\frac{3}{10}[/tex]
[tex]\frac{15}{10} -\frac{12}{10} = \frac{3}{10}[/tex]
Step-by-step explanation:
Given
[tex]\frac{3}{2} - \frac{6}{5}[/tex]
Now the L.C.M = 10
= [tex]\frac{15-12}{10}[/tex]
= [tex]\frac{15}{10} -\frac{12}{10} = \frac{3}{10}[/tex]
Enter the value of x that makes the given equation true.
3(5 - x) = 7x - 2
Answer:
exact form: x=17/10
Decimal form: x=1.7
mixed number form: 1 7/10
Answer:
x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)
Step-by-step explanation:
3(5-x) = 7x - 2
3 * 5 - 3* x = 7x - 2 (brackets means multiply)
15 - 3x = 7x - 2 (when over equal sign negative changed to positive)
15 + 2 = 7x + 3x
17/10 = 10x/10 (cross-cancel cuz u tryna isolate the x)
17/10 = x

do the ratios 8/16 and 2/4 form a proportion
Answer:
Step-by-step explanation:
8/16=8:16
2/4=2:4
Answer:
Yes, the ratios 2/4 and 8/16 form a proportion. To check if two ratios form a proportion, you can cross-multiply and see if the products are equal. In this case, 2 x 16 = 4 x 8 = 32, so the products are equal. Therefore, the ratios form a proportion.

Answer:
a). Distance round one loop = 141.37 meters
b). Distance covered = 3534.29 meters
Step-by-step explanation:
Diameter of the given track = 45 meters
a). Distance round one loop of the track = circumference of the circle
Circumference of a circle = π × (Diameter)
= π × (45)
= 141.37 meters
b). Distance covered by going around the track 25 times = 25 × distance in one loop of the track
= 25 × 141.37
= 3534.29 meters

Answer:
≈ 50.7 cm²
Step-by-step explanation:
The area (A) of Δ XYZ is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height ), that is
A = [tex]\frac{1}{2}[/tex] × XY × YZ
Calculate YZ using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{YZ}{XY}[/tex] = [tex]\frac{x}{11}[/tex] ( multiply both sides by 11 )
11 × tan40° = x , that is
YZ ≈ 9.23 cm
Thus
A = [tex]\frac{1}{2}[/tex] × 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )

Show that the two shorter sides in triangle A have the same length as the two shorter sides in triangle B
Answer:
Step-by-step explanation:
a). Let the unknown side of triangle A = x cm
And unknown side of triangle B = y cm
By applying Pythagoras theorem in triangle A,
13² = 12² + x²
x² = 169 - 144
x² = 25 ⇒ x = 5 cm
By applying Pythagoras theorem in triangle B,
y² = 5² + 12²
y² = 25 + 144
y = √169
y = 13 cm
Therefore, smaller sides of these triangles measure 5 cm and 12 cm and they are same in measure.
b). Since, corresponding sides of both the triangles are congruent,
By SSS property of congruence, both the triangles will be congruent.
15(n−10)=6−312 what is n
Answer:
ATQ= 15 is 1/5 and 312 is 3/12 sorry for that
1/5(N-10)=6-3/12
1/5N -2= 6/1 - 3/12
1/5N-2 = 72 -3/12 = 69/12
69/2 = 5.75
1/5N = 5.75-2 = 3.75
N= 3.75/.2

what does is the c ? c + 13 = -17
Step-by-step explanation:
c + 13 = - 17
c = - 17 - 13
Therefore c = -30
Hope it will help :)
Answer:
c is equal to negative thirty.
Step-by-step explanation:
You can find out what c is by subtracting 13 from both sides of the equation:
c + 13 = -17
c + 13 - 13 = -17 - 13
c + 0 = -30
c = -30
