Estimate the figure to the nearest whole number

1 answer:

3 0

That means that, for example:

if your number is 49 the nearest whole number would be 50.

so by saying estimate the figure to the nearest whole number , they are basically saying find your nearest whole number.

Marizza181 [45]

Set up a proportion.

pounds / milligrams of medicine

195/279 = 130/x

195x = 279 times 130
195x =36,270
x = 36,270/195
x = 186

A patient weighing 130 pounds needs 186 milligrams of medicine.

$\\ \sf\longmapsto y=kx$

$\\ \sf\longmapsto k=\dfrac{y}{x}$

put values

$\\ \sf\longmapsto k=\dfrac{20}{0.4}$

$\\ \sf\longmapsto k=50$

Alright,

(a) 2x+4(x-1)=2
2x+4x-4=2---- Distrubution of 4(x-1)
6x-4=2---- Combining like terms
6x=6---- Making -4 equal 0 by adding +4 to both sides
x=1---- Divide the coefficiant (6)

(b) 25-x=15-(3x+10)
25-x=15-3x-10----Distribute the -1
25-x=5-3x---- Combine like terms
25=5-2x---- Make -x equal 0 by adding +x to both sides
20=-2x---- Make 5 equal zero by subtracting 5 (or adding -5) to both sides
-10=x---- Divide by the coefficiant (-2)

(c) 4x= 2x+2x+5(x-x)
4x=2x+2x+5(0)---- Distribute. Alright this might look hard but realy it is 1x-1x so the answer is 0
4x=2x+2x---- 5 times 0 is 0
4x=4x---- Combine like terms
x=x ---- divide by the coefficiant

Alright! Hope this helps! ;)
