Answer:
∠ DBC = 16°
Step-by-step explanation:
∠ ABD + ∠ DBC = ∠ ABC , substitute values
2x + 15 + x - 30 = 123 , that is
3x - 15 = 123 ( add 15 to both sides )
3x = 138 ( divide both sides by 3 )
x = 46
Thus
∠ DBC = x - 30 = 46 - 30 = 16°

Answers
Answer:
m is 7
Step-by-step explanation:
The length of RS is 32.
Given,
M is the bisector of RS
RM = 6x - 2
MS = 3x + 7
We need to find RS.
What does it mean to be a bisector point in a line?A bisector point in a line divides the line into two equal halves.
Example:
A_____B_____C
B = midpoint
AB = BC
AC = AB + BC
We have,
R_____M______S
RS = RM + MS
M = bisector
RM = MS
RM = 6x - 2
MS = 3x + 7
6x - 2 = 3x + 7
6x - 3x = 7 + 2
3x = 9
x = 9/3
x = 3
Now,
RS = RM + MS
RS = 6x - 2 + 3x + 7
RS = 9x + 5
RS = 9 x 3 + 5
RS = 27 + 5
RS = 32
Thus the length of RS is 32.

Solve for x in the following triangle.
Answers
Answer:
x = 12
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
8 + 6x is an exterior angle of the triangle, thus
8 + 6x = 30 + 4x + 2 = 4x + 32 ( subtract 4x from both sides )
8 + 2x = 32 ( subtract 8 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12

Answers
Answer:
D. 3h + 2 ≥ 14
Step-by-step explanation:
Cost of Bottle water = $2
Cost of Hot dogs = $3
Number of hot dogs bought = h
Total cost of hot dogs = price × quantity
= 3 * h
= 3h
Jeff did not spend more than $14
Total cost of bottle water and hot dogs
3h + 2 ≥14
The correct answer is D

Kelly needs to travel 12 miles. Taxi A charges $3.00 plus $0.30 every 1/9 mile. Taxi B charges $3.25 plus $0.20 every 1/9 mile. How much money (in dollars) does kelly save by using taxi B instead of taxi A? (PLEASE HELP ASAP)
Answers
Answer:
$10.55
Step-by-step explanation:
Total miles traveled = 12miles
If taxi A charges $0.3 for every 1/9 mile, then for 12 Miles, he will charge;
12×0.3/(1/9)
= 12×0.3×9
= 108×0.3
= $32.4
Amount charged initially = $3.00
Total charge by Taxi A = $32.4+$3.00
Total charge by Taxi A = $35.4
If taxi B charges $0.2 for every 1/9 mile, then for 12 Miles, he will charge;
12×0.2/(1/9)
= 12×0.2×9
= 108×0.2
= $21.6
Amount charged initially = $3.25
Total charge by Taxi B = $21.6+$3.25
Total charge by Taxi B = $24.85
Total money saved by Kelly = Amount charged by Taxi A - Amount charged by Taxi B
Total money saved by Kelly = $35.4-$24.85
= $10.55
Hence Kelly saved $10.55 using taxi B

A rectangle is a two-dimensional shape where the length and width are different.
The length and width of the larger rectangle are 4.8 cm and 8.4 cm.
The area of the larger rectangle is 40.32 cm².
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Two similar rectangles:
Smaller rectangles:
Length = 4 cm
Width = 7 cm
Larger rectangles:
Length = 4.8 cm
We need to find the width of the larger rectangle.
Since the two rectangles are similar.
4 cm = 4.8 cm
Multiply 7/4 on both sides.
7/4 x 4cm = 7/4 x 4.8 cm
7 cm = 8.4 cm
Now,
Larger rectangle:
Length = 4.8 cm
Width = 8.4 cm
Now,
The area of the larger rectangle:
Area = Length x width
Area = 4.8 x 8.4
Area = 40.32 cm²
Thus,
The area of the larger rectangle is 40.32 cm².
