Solve: 30x < 200. Start with trial values for x and find the solution set.
Answer
Step 1: Test whole-number values because x is the number of rice packets. Step 2: x = 0 gives 0 < 200, true. Step 3: x = 1 gives 30 < 200, true. Step 4: x = 2 gives 60 < 200, true. Step 5: x = 3 gives…
हल करें: 30x < 200. x के लिए परीक्षण मूल्यों से शुरू करें और समाधान सेट ज्ञात करें।
Answer
चरण 1: पूर्ण-संख्या मानों का परीक्षण करें क्योंकि x चावल के पैकेटों की संख्या है। चरण 2: x = 0 gives 0 < 200, सही। चरण 3: x = 1 gives 30 < 200, सही। चरण 4: x = 2 gives 60 < 200, सही। चरण 5: x = 3 give…
Solve: 30x < 200 when x is a natural number.
Answer
Step 1: Divide both sides by 30. 30x < 200 x < 20/3 Step 2: Since x is a natural number, only positive whole numbers are allowed. Step 3: Values less than 20/3 are 1, 2, 3, 4, 5, 6. Answer: {1,2,3,4,5…
हल करें: 30x < 200 जब x एक प्राकृत संख्या है।
Answer
चरण 1: दोनों तरफ 30 से भाग दीजिए। 30x < 200 x < 20/3 चरण 2: चूँकि x एक प्राकृत संख्या है, इसलिए केवल धनात्मक पूर्ण संख्याओं की अनुमति है। चरण 3: 20/3 से कम मान 1, 2, 3, 4, 5, 6 हैं। उत्तर: {1,2,3,4,5,…
Solve: 30x < 200 when x is an integer.
Answer
Step 1: Divide both sides by 30. 30x < 200 x < 20/3 Step 2: Since x is an integer, all integers less than 20/3 work. Step 3: The integers are ...,-3,-2,-1,0,1,2,3,4,5,6. Answer: {...,-3,-2,-1,0,1,2,3,…
हल करें: 30x < 200 जब x एक पूर्णांक है।
Answer
चरण 1: दोनों तरफ 30 से भाग दीजिए। 30x < 200 x < 20/3 चरण 2: चूँकि x एक पूर्णांक है, इसलिए 20/3 से कम सभी पूर्णांक काम करते हैं। चरण 3: पूर्णांक हैं ...,-3,-2,-1,0,1,2,3,4,5,6. उत्तर: {...,-3,-2,-1,0,1…
Why is 30x < 200 not an equation?
Answer
Step 1: An equation must contain the sign of equality. Step 2: 30x < 200 uses the sign <, not =. Step 3: So it is an inequality, not an equation. Answer: It is not an equation because it lacks the sig…
30x < 200 एक समीकरण क्यों नहीं है?
Answer
चरण 1: एक समीकरण में समानता का चिह्न होना आवश्यक है। चरण 2: 30x < 200 में < चिह्न का उपयोग किया गया है, कोईt =. नहीं। चरण 3: इसलिए यह एक असमानता है, एक समीकरण नहीं। उत्तर: यह एक समीकरण नहीं है क्योंकि…
