whats the answer to 1+3x=-2(x+7)
Answer:
x = -3
Step-by-step explanation:
1+3x=-2(x+7)
Distribute
1+3x = -2x-14
Add 2x to each side
1+3x+2x = -2x+2x-14
1+5x = -14
Subtract 1 from each side
1-1+5x= -14-1
5x = -15
Divide each side by 5
5x/5 = -15/5
x = -3

Answer:
Angle O = 72°, Angle M = 18°, Angle N = 90°
Step-by-step explanation:
According to the angle sum theorem, all interior angles of a euclidean triangle always add up to 180°.
given 5(Angle M) = Angle N, and 4(Angle M) = Angle O, you can substitute these equations into the equation defined by this theorem, Angle M + Angle N + Angle O = 180°
. Angle M + 5(Angle M) + 4(Angle M) = 180°
10(Angle M) = 180°.
then you divide. Angle M = 18°
with this statement. you can substitute this into the other equations to get the other answers.
5(18°) = Angle N, 4(18°) = Angle O.
90° = Angle N, 72° = Angle O.

Answer:

107/135
(Decimal: 0.792593)
Step-by-step explanation:
Answer:
a. 19/20
B. -5.78
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by its reciprocal. i.e. [tex]\frac{-\frac{2}{3} }{-\frac{8}{9} } =-\frac{2}{3} *-\frac{9}{8} = \frac{3}{4}[/tex] to add to 1/5, change both denominators to 20.
[tex]\frac{3}{4} * \frac{5}{5} = \frac{15}{20}[/tex]
[tex]\frac{1}{5} *\frac{4}{4} =\frac{4}{20}[/tex]
[tex]\frac{15}{20} +\frac{4}{20} = \frac{19}{20}[/tex]
B. Convert all to decimals, then work from the inside out because of the parentheses. -1.6 + 4 = 2.4, 2.4(-0.3) = -0.72, -0.72 - 6.5 = -5.78

how many even integers n satisfy the inequality | 2N - 1 | < 5?
Answer:
-2 is the answer
Step-by-step explanation:
There is only one even integer i.e 2 that satisfies the given inequality | 2N - 1 | < 5.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Inequality | 2N - 1 | < 5 which is given in the question.
The positive solution to inequality as :
⇒ 2N - 1 < 5
⇒ 2N < 5 + 1
⇒ 2N < 6
⇒ N < 3
Therefore, N = 2 i.e an even integer satisfies the inequality.
The negative solution to inequality as :
⇒ -(2N - 1) < 5
⇒ (2N - 1) > -5
⇒ 2N > -5 + 1
⇒ 2N > - 4
⇒ N > -2
Therefore, N = 2 i.e an even integer satisfies the inequality.
Therefore, only one even integer satisfies the given inequality | 2N - 1 | < 5.

A) 4 m
B) 4 km
C) 4 cm
D) 4 mm
The dimension of the bus, car, and so on is measured in meters because the 1 or 2 centimeters can be neglected. Then the correct option is A.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The measurement of the object is taken by its length. For example - the distance between the cities is measured in kilometers because the 1 or 2 meters can be neglected.
Similarly, the dimension of the bus, car, and so on is measured in meters because the 1 or 2 centimeters can be neglected.
Then the correct option is A.

Dariya
Answer:
Benito's line has a slope of three
Step-by-step explanation:
Slope can be determined by the rate of change. Because Benito's first point is 0,1 that means that x = 0 and y = -1. Benito's second point is 1,2 which means that x = 1 and y = 2. To determine the slope, you need to look at the change of y. We can see that y=-1 in the first point, and y=2 in the second point. This is an increase of three, which means that Benito's line has a slope of three.
Answer: Benito:On a coordinate plane, a line goes through points
