Marco is 3 inches tall. There are 2.54 centimeters in 1 inch. What is marcos height in centimeters?
Answer:
The answer is 190.5cm
Step-by-step explanation:
o solve this problem, we first need to convert marco's height to inches.
there are 12 inches in 1 foot.
multiply.
notice how ft cancel out because they are in opposite positions of the fraction.
add 72+3 to get marco's height in inches.
marco is 75inches.
with this information, we can solve for his height in cm.
write an equation.
solve.
marco is 190.5centimeters

-5x-9 is greater than or equal to -4
Answer x is less than or equal to -1
Step-by-step explanation:
-5x-9 -4
-5x-9+9 -4+9
-5x 5
-5x/-5x 5/-5
x less than or equal to -1
Answer:
x [tex]\leq[/tex] -1
Step-by-step explanation:
(-5x - 9) [tex]\geq[/tex] -4
add 9 to both sides of the equation
-5x-9 [tex]\geq[/tex] -4
+9 +9
--------------------
the -9 and +9 cancel out
-5x [tex]\geq[/tex] 5
then, divide both sides by -5 to get x
-5x [tex]\geq[/tex] 5
------ -------
-5 -5
x [tex]\leq[/tex] -1
by the way, the sign changed from [tex]\geq[/tex] to [tex]\leq[/tex] because we divided by a negative number to get x.

The diagram shows two parallel lines cut by a transversal. One angle measure is shown.
Two lines that do not intersect. A third line intersects with both lines.
Find the values of a, b, c, d, e, f, and g. Do not include any labels or degree symbols.
a=
b=
c=
d=
e=
f=
g=
Answer:
See below
Step-by-step explanation:
a + 54° = 180° [Angles on a straight line]
a = 180 - 54
a = 126°
a + b = 180 [Angles on a straight line add up to 180 degrees]
126 + b = 180
b = 180 - 126
b = 54°
c° = a° [Vertically opposite angles are equal]
c° = 126°
d = 54° [Corresponding angles are equal]
e = a [Corresponding angles are equal]
e = 126°
f = b [Corresponding angles are equal]
f = 54°
g = c [Corresponding angles]
g = 126°

What is the measure of the angle
Hey! The measure of the angle is 127
The angle is a total of 180 degrees.
We have to find the total of what's in between the two blue lines.
To make it easier, we can take the total of what's not in the blue lines, 53, and subtract it from 180. This gives us 127. So in between both the blue lines, measures 127. Or, you can just count up from 53 to 180 individually.

The figures are similar. Find x ,
Answer:
8 cm
Step-by-step explanation:
Hello there! :)
We are given that these figures are similar.
It means that the sides are proportional. So
[tex]\frac{4}{6} =\frac{6}{x}[/tex]
Cross-multiply:
4x=36
Divide both sides by 4 to isolate x:
x=9 cm

A local foundation organized a lunch party for all the kids in the community. They ordered a total of 500 burger meals. They ordered plain burgers at $1.75 each cheeseburgers at $2.50 each, and chicken burgers
at $3.20 each. They ordered mostly cheeseburgers, and 100 fewer chicken burgers than plain burgers. The total order came to $1.172.50.
Define the variables and write a system of equations to represent the
situation.
9514 1404 393
Answer:
x + y + z = 5002.50x +1.75y +3.20z = 1172.500x +y -z = 100Step-by-step explanation:
Let x, y, z represent the numbers of cheeseburgers, plain burgers, and chicken burgers ordered for the party.
We have three relations given. Each can be used to write an equation.
x + y + z = 500 . . . . . . . . . a total of 500 meals were ordered
2.50x +1.75y +3.20z = 1172.50 . . . . . the total cost
0x +y -z = 100 . . . . . . . . . . 100 fewer chicken were ordered than plain
_____
Additional comment
We put the coefficient of x as 0 in the last equation to facilitate writing this system as an augmented matrix.
[tex]\left[\begin{array}{ccc|c}1&1&1&500\\2.50&1.75&3.20&1172.50\\0&1&-1&100\end{array}\right][/tex]
The solution is (x, y, z) = (300, 150, 50).

The sum of three numbers is 66. The second number is twice the first and six less than the third. find the numbers
Step-by-step explanation:
let the 1st number be x
and,
2nd number = 2x
3rd number = 2x + 6
their sum = 66
so, after inserting the values we got
→ x + 2x + 2x + 6 = 66
→ 5x + 6 = 66
→ 5x = 66 - 6 = 60
→ x = 60/5 = 12
→ x = 12
therefore,
1st number = x = 12
2nd number = 2x = 12 × 2 = 24
3rd number = 2x + 6 = 24 + 6 = 30
hope this answer helps you dear...take care and may u have a great day ahead!
Solve the inequality 5z+8≥-7
Answer:

5z≥−15
3 Divide both sides by 55.
z≥− 15/5
