HELPPP HELPP!! WHAT IS THE VALUE OF X AND W???
Answer:
w = 42
x = 29
Step-by-step explanation:
We know that w + 138 must equal 180, so we get 42 for w. Then we know that 19 + x + 2 = 90, and w = 42. So if we add 42 + 19, and subtract that from 90, we get 29. Hope this helps!

I have 5digits My name is worth 90,000 my two is worth 2 thousand one of my sevens is worth 70 the other is worth 10 times as much my other digit is a six what number am I
Answer:
92776
Step-by-step explanation:
From the given question,
The analysis of the given question can be computed as follows:
I have 5 digits
My name is worth 90000
my two is worth 2000
one of my seven is worth 70
and the other is worth 10 times
as much i.e 10× 70 = 700 700
my other digit is six 6
What number am I?
So, we are expected to look for the summation of all the numbers
i.e 90000 + 2000 + 70 + 700 + 6
= 92776
Thus, the number is 92776

Muson
o
9:00
Answer:
total dogs= 2
total pets= 2+4+5=11
so, the ratio of dogs to all pets = 2/11
Step-by-step explanation:
Based on the number of all animals in the shop as well as the number of dogs, we can infer that the ratio of dogs to the others is 2 : 11
The first thing to do is to find the total number of animals in the shop:
= Dogs + Cats + Hamsters
= 2 + 4 + 5
= 11 animals
The ratio of dogs to the rest of the animals is:
= Number of dogs : Number of animals
= 2 : 11
= 2 : 11
In conclusion, the ratio is 2:11.

Step-by-step explanation:
if angle LMPis 11 degrees more than angle NMP and angle NML is 137 find each measure.
Answer:
angle NMP = 63°
angle LMP = 74°
Step-by-step explanation:
Let angle NMP be x° . It's given that angle LMP is 11° more than angle NMP. So, angle LMP = x° + 11°
But angle NML = 137°.
So,
angle NMP + angle LMP = 137°
=> x° + x° + 11° = 137°
=> 2x° + 11° = 137°
=> 2x° = 137° - 11°
= 126°
=> x° = 126/2 = 63°
angle NMP = 63°
angle LMP = 63 + 11 = 74°

The width of a rectangle measures (2.5u+9.8)(2.5u+9.8) centimeters, and its length measures (1.5u+3.9)(1.5u+3.9) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Solution,
We have,
Width of rectangle, b = (2.5u+9.8) cm
Length of rectangle, l = (1.5u+3.9) cm
We need to find the expression for the perimeter of the rectangle. The formula for the perimeter of a rectangle is given by:
Perimeter = 2(l+b)
P = 2[(2.5u+9.8)+(1.5u+3.9)]
Collecting like terms
P = 2[(2.5u+1.5u)+(9.8+3.9)]
P=2(4u+13.7)
⇒ P = 8u+27.4
So, the expression for the perimeter of the rectangle is (8u+27.4) cm.

Add 4 to a term to get the next term
Each Term is the sum of the two preceding terms plus 5
O Multiply a term by 2 and add 1 to get the next term
Answer:
multiply a term by 2 and add 1 to get the next term
Step-by-step explanation:
3×2=6 +1 =7
7×2=14+1= 15
15×2=30+1=31
Answer:
Multiply a term by 2 and add 1 to get the next term
Step-by-step explanation:
The first differences of terms are ...
7 -3 = 4
15 -7 = 8
31 -15 = 16
We notice that these increase by a factor of 2. This signifies an exponential sequence. That factor (2) will be the value that each term is multiplied by to get the next. This eliminates the choices "add 4" and "multiply a term by 3 ...".
Trying the remaining two choices, we find that the one that fits is the one shown above.
3+7 ≠ 15, so "the sum of the two preceding terms" doesn't work
2(3) +1 = 7; 2(7) +1 = 15; 2(15) +1 = 31, so "multiply by 2 and add 1" works fine

Charlie has a collection of books that he wishes to display in a narrow bookcase with shelves of width 56cm. The thickest books are no more than 16cm wide and, when placed side by side, the entire collection takes up 2.4m. Find, with justification, the minimum number of shelves required to guarantee that all of the books can be displayed in the bookcase.
Answer:
5 shelves
Step-by-step explanation:
Given the following :
Width of shelves = 56cm
Maximum thickness of books = 16cm
When placed side-by-side, the entire collection of books takes up 2.4m
Minimum number of shelves required to guarantee that all of the books can be displayed in the book case.
Entire book collection = 2.4m = (2.4 × 100) = 240cm
Width of shelf = 56cm
In other to guarantee that the bookshelf contains all the books, we can assume that the each book is of maximum width, 16cm
Hence, maximum number of books each shelf can hold with guarantee
Width of shelf / max. Width of book
= 56cm / 16cm = 3.5
Hence, a shelf can hold 3 books with full guarantee.
If books are all 16cm thick, then the number of books ;
240 cm / 16 cm = 15 books
If one shelf can hold 3 books, then,
15/3 = 5 shelves are required to hold the books with maximum guarantee.

Anusha is walking on a hiking trail at a rate of Three-fourths miles in One-fourth hour. At this rate, how far will Anusha walk in an hour?
Answer:
Step-by-step explanation:
3/4 + 3/4 + 3/4 + 3/4 = 12/4 = 3. She will walk 3 miles in an hour.
The distance that Anusha covered in one hour is 3 miles
If Anusha is walking on a hiking trail at a rate of three-fourths miles in One-fourth hour, this is expressed as:
3/4 miles = 1/4 hours
We need to get the rate of Aisha that is the distance traveled in an hour
x = 1 hour
Divide both expressions
3/4x = 1/4
Cross multiply
4x = 3 * 4
4x = 12
x = 12/4
x = 3
Hence the distance that Anusha covered in one hour is 3 miles
