Answer:24+4x
Step-by-step explanation:
a=5. PHOTO
b=7. PHOTO
a1=5+x. FRAME
b1=7+x. FRAME
Pf=2*(a1+b1)
Pf=2*(5+x+7+x)
Pf=2*(12+2x)
---------Pf=24+4x. - - - - - - PERIMETER OF FRAME
Answer:
D
Step-by-step explanation:
the end result of a radical can never be negative unless the negative sign shows outside of the radical
The major math strands for a sixth grade curriculum are number sense and operations, algebra, geometry and spatial sense, measurement, and functions and probability. While these math strands might surprise you, they cover the basics of what a sixth grader should learn in math.
Students in 6th grade should already master math facts to help them understand more advanced math concepts. Some of the skills you should ensure mastery on for 6th graders include:
Multiplying 3-digit by 2-digit numbers
Comparing, rounding, and performing basic operations with decimals
Fractions: adding, subtracting, simplifying, comparing, etc.
Data analysis using bar graphs, line graphs, Venn diagrams, etc.
Geometry: using a protractor, sorting and classifying triangles, polygons, quadrilaterals

Math Objectives for 6th Grade
At the beginning of the school year you should define some 6th grade math goals and objectives for your student. Below is a general idea of the 6th grade math objectives your child should be working towards.
Understand pre-algebra concepts such as using variables to simplify expressions
Identify decimal place value; compare and order decimals using a number line
Use frequency tables and identify appropriate intervals
Know how to use ratios and rates to compare data
Locate and plot points on a coordinate graph using ordered pairs
Understand the relationship between fractions, decimals, and percents
Also tell what you need that needs to be simplified. Be specific.
Answer:
n ≥ -12
Step-by-step explanation:
Change the less than or equals sign to an equals sign
-7(n+7) = 35
Use distributive property to figure out what -7(n+7) equals
-7n-49 = 35
Add 49 to both sides
-7n = 84
Divide both sides by -7
n = -12
Bkuz you want n -7(n+) to be less than or equal to 35 you have to change the equals sign in n = -12 to a greater or equal to sign
Hope this helps!
Answer:
X=61.2
Step-by-step explanation:
x/85 = 72/100
x*100/8500 = 6120/8500
x*100 must equal 6120 therefore x must be 61.2 because 61.2 * 100 is 6120
